Facile synthesis of a hierarchical CuS/CuSCN nanocomposite with advanced energy storage properties

We introduce CuS/CuSCN nanocomposites as active materials in pseudocapacitors, in which the redox reactions of both CuS and CuSCN simultaneously contribute to energy storage. This nanocomposite is prepared using an in situ methodology via facile, low-energy-consuming green nanochemistry. The CuS/CuSCN nanocomposites offer a high capacitance compared to their individual constituents. CuS nanorods (?15 nm) are anchored on the surface of CuSCN nanosheets (?100 nm) and they interconnect the CuSCN nanosheets, producing mesoporous nanoclusters with a large surface area, thus improving the charge transfer efficiency. The CuS/CuSCN nanocomposites exhibit high electrical conductivity and strong redox reactivity, and in particular, the pseudocapacitor with a compositional ratio of 1:1 exhibits the highest charge transfer efficiency. Consequently, the 11 CuS/CuSCN active material exhibits a high energy density (approximately 63 W h kg-1) and a high power density (1.9 kW kg-1 at 9.0 W h kg-1) as a single electrode. The highest specific capacitance is measured to be 1787.3 F g-1 in the single electrode. Furthermore, an aqueous asymmetric hybrid supercapacitor based on the CuS/CuSCN 1:1//activated carbon (AC) shows an approximately four times increase in the power density (7.9 kW kg-1), compared to the single electrode.

High-Efficiency Fullerene Solar Cells Enabled by a Spontaneously Formed Mesostructured CuSCN-Nanowire Heterointerface

Fullerenes and their derivatives are widely used as electron acceptors in bulk-heterojunction organic solar cells as they combine high electron mobility with good solubility and miscibility with relevant semiconducting polymers. However, studies on the use of fullerenes as the sole photogeneration and charge-carrier material are scarce. Here, a new type of solution-processed small-molecule solar cell based on the two most commonly used methanofullerenes, namely [6,6]-phenyl-C61-butyric acid methyl ester (PC60BM) and [6,6]-phenyl-C71-butyric acid methyl ester (PC70BM), as the light absorbing materials, is reported. First, it is shown that both fullerene derivatives exhibit excellent ambipolar charge transport with balanced hole and electron mobilities. When the two derivatives are spin-coated over the wide bandgap p-type semiconductor copper (I) thiocyanate (CuSCN), cells with power conversion efficiency (PCE) of ?1%, are obtained. Blending the CuSCN with PC70BM is shown to increase the performance further yielding cells with an open-circuit voltage of ?0.93 V and a PCE of 5.4%. Microstructural analysis reveals that the key to this success is the spontaneous formation of a unique mesostructured p?n-like heterointerface between CuSCN and PC70BM. The findings pave the way to an exciting new class of single photoactive material based solar cells.

DFT calculations of Cun Om0 / + clusters: Evidence for Cu2O building blocks

The structures of Cun Om+ / 0 and Cun Om Hl+ / 0 clusters are obtained by DFT calculations. Clusters with even and odd number of copper atoms can be, respectively represented as (Cu2 O)n+ and [(Cu2O)nCu]+. The latter are highly symmetrical and show positive charge uniformly distributed on the Cu atoms, whereas in the former, one of the Cu2O subunits exhibits a higher positive charge. It is found that the divalent oxygen of Cu2O is the reactive site involved in cluster growing. The structures of Cun Om H2+ / 0 and Cu2nOnH+/0, correspond, respectively to hydrated and hydrogenated clusters.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 1317-39-1 is helpful to your research.

CuSCN modified PEDOT:PSS to improve the efficiency of low temperature processed perovskite solar cells

The energy structure of PEDOT:PSS limits the perovskite solar cell (PSC) performance based on inverted FTO/PEDOT:PSS/perovskite/PCBM structure. Here, inorganic CuSCN is modified on PEDOT:PSS using spin-coating method under low temperature, which is compatible with the low temperature fabrication of PSC. Modification CuSCN guarantees the light harvesting of perovskite layer because of the transparency of CuSCN and good crystalline of perovskite film on CuSCN/PEDOT:PSS substrate. Furthermore, CuSCN effectively changes the energy states of PEDOT:PSS to decrease the energy loss during charge transport, promoting the charge transfer at the same time. Based on the improved charge transport and reduced energy loss, the photovoltaic property of PSC based on CuSCN/PEDOT:PSS reaches the optimized efficiency of 10.9%, much better than the control PEDOT:PSS-based device with 9.1% performance (AM1.5, 1sun).

Silver Bismuth Sulfoiodide Solar Cells: Tuning Optoelectronic Properties by Sulfide Modification for Enhanced Photovoltaic Performance

Silver bismuth iodides (AgaBibIa+3b) are nontoxic and comparatively cheap photovoltaic materials, but their wide bandgaps and downshifted valence band edges limit their performance as light absorbers in solar cells. Herein, a strategy is introduced to tune the optoelectronic properties of AgaBibIa+3b by partial anionic substitution with the sulfide dianion. A consistent narrowing of the bandgap by 0.1 eV and an upshift of the valence band edge by 0.1?0.3 eV upon modification with sulfide are demonstrated for AgBiI4, Ag2BiI5, Ag3BiI6, and AgBi2I7 compositions. Solar cells based on silver bismuth sulfoiodides embedded into a mesoporous TiO2 electron-transporting scaffold, and a poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] hole-transporting layer significantly outperform devices based on sulfide-free materials, mainly due to enhancements in the photocurrent by up to 48%. A power conversion efficiency of 5.44 ± 0.07% (Jsc = 14.6 ± 0.1 mA cm?2; Voc = 569 ± 3 mV; fill factor = 65.7 ± 0.3%) under 1 sun irradiation and stability under ambient conditions for over a month are demonstrated. The results reported herein indicate that further improvements should be possible with this new class of photovoltaic materials upon advances in the synthetic procedures and an increase in the level of sulfide anionic substitution.

Electronic Modulation of Electrocatalytically Active Center of Cu7S4 Nanodisks by Cobalt-Doping for Highly Efficient Oxygen Evolution Reaction

Cu-based electrocatalysts have seldom been studied for water oxidation because of their inferior activity and poor stability regardless of their low cost and environmentally benign nature. Therefore, exploring an efficient way to improve the activity of Cu-based electrocatalysts is very important for their practical application. Modifying electronic structure of the electrocatalytically active center of electrocatalysts by metal doping to favor the electron transfer between catalyst active sites and electrode is an important approach to optimize hydrogen and oxygen species adsorption energy, thus leading to the enhanced intrinsic electrocatalytic activity. Herein, Co-doped Cu7S4 nanodisks were synthesized and investigated as highly efficient electrocatalyst for oxygen evolution reaction (OER) due to the optimized electronic structure of the active center. Density-functional theory (DFT) calculations reveal that Co-engineered Cu7S4 could accelerate electron transfer between Co and Cu sites, thus decrease the energy barriers of intermediates and products during OER, which are crucial for enhanced catalytic properties. As expected, Co-engineered Cu7S4 nanodisks exhibit a low overpotential of 270 mV to achieve current density of 10 mA cm-2 as well as decreased Tafel slope and enhanced turnover frequencies as compared to bare Cu7S4. This discovery not only provides low-cost and efficient Cu-based electrocatalyst by Co doping, but also exhibits an in-depth insight into the mechanism of the enhanced OER properties.

N2O decomposition over CuO/CeO2catalyst: New insights into reaction mechanism and inhibiting action of H2O and NO by operando techniques

In this work, a combination of ex situ (STEM-EELS, STEM-EDX, H2-TPR and XPS), in situ (CO-DRIFTS) and operando (DR UV-vis and DRIFTS) approaches was used to probe the active sites and determine the mechanism of N2O decomposition over highly active 4 wt.% Cu/CeO2catalyst. In addition, reaction pathways of catalyst deactivation in the presence of NO and H2O were identified. The results of operando DR UV-vis spectroscopic tests suggest that [Cu-O-Cu]2+sites play a crucial role in catalytic N2O decomposition pathway. Due to exposure of {1 0 0} and {1 1 0} high-energy surface planes, nanorod-shaped CeO2support simultaneously exhibits enhancement of CuO/CeO2redox properties through the presence of Ce3+/Ce4+redox pair. Its dominant role of binuclear Cu+site regeneration through the recombination and desorption of molecular oxygen is accompanied by its minor active participation in direct N2O decomposition. NO and H2O have completely different inhibiting action on the N2O decomposition reaction. Water molecules strongly and dissociatively bind to oxygen vacancy sites of CeO2and block further oxygen transfer as well as regeneration of catalyst active sites. On the other hand, the effect of NO is expressed through competitive oxidation to NO2, which consumes labile oxygen from CeO2and decelerates [Cu+Cu+] active site regeneration.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process.
