One-pot synthesis of monodisperse copper?silver alloy nanoparticles and their composition-dependent electrocatalytic activity for oxygen reduction reaction

Development of an economical, well-defined and efficient electrocatalyst having a potential to replace Pt/C is crucial for oxygen reduction reaction (ORR). In this respect, we report herein one-pot wet-chemical protocol for the composition-controlled synthesis of monodisperse CuAg alloy nanoparticles (NPs) and their composition-dependent electrocatalytic activities in ORR for the first time under an alkaline condition. The presented synthetic procedure yields CuAg NPs that exhibit monodisperse size distribution with an average particle diameter of ?8 nm. Almost homogenous CuAg alloy formation is proved by using many advanced analytical techniques despite the considerable lattice mismatch between Cu and Ag. At all compositions investigated, the ORR activities of CuAg electrocatalysts are found to be significantly higher than monometallic Ag NPs. Improved ORR kinetics of CuAg alloy NPs are demonstrated by Tafel slopes (85 mV/dec for Cu30Ag70, 84 mV/dec for Cu40Ag60 and 78 mV/dec for Cu60Ag40 which are all smaller than that of monometallic Ag (113 mV/dec). Electrochemical impedance measurements support these findings and represent that charge transfer resistance strongly depends on composition of CuAg electrocatalyst. The ORR activity and surface analysis results put Cu40Ag60 forward since Cu oxidation is suppressed in Cu40Ag60 NPs, caused by Ag enhancement in the surface.

Discrete Supertetrahedral T5 Selenide Clusters and Their Se/S Solid Solutions: Ionic-Liquid-Assisted Precursor Route Syntheses and Photocatalytic Properties

Although supertetrahedral Tn sulfide clusters (n=2?6) have been extensively explored, the synthesis of Tn selenide clusters with n>4 has not been achieved thus far. Reported here are ionic-liquid (IL)-assisted precursor route syntheses, characterizations, and the photocatalytic properties of six new M-In-Q (M=Cu or Cd; Q=Se or Se/S) chalcogenide compounds, namely [Bmmim]12Cu5In30Q52Cl3(Im) (Q=Se (T5-1), Se48.5S3.5 (T5-2); Bmmim=1-butyl-2,3-dimethylimidazolium, Im=imidazole), [Bmmim]11Cd6In28Q52Cl3(MIm) (Q=Se (T5-3), Se28.5S23.5 (T5-4), Se16S36 (T5-5); MIm=1-methylimidazole), and [Bmmim]9Cd6In28Se8S44Cl(MIm)3 (T5-6). The cluster compounds T5-1 and T5-3 represent the largest molecular supertetrahedral Tn selenide clusters to date. Under visible-light illumination, the Cu-In-Q compounds showed photocatalytic activity towards the decomposition of crystal violet, whereas the Cd-In-Q compounds exhibited good photocatalytic H2 evolution activity. Interestingly, the experimental results show that the photocatalytic performances of the selenide/sulfide solid solutions were significantly better than those of their selenide analogues, for example, the degradation time of the organic dye with T5-2 was much shorter than that with T5-1, whereas the photocatalytic H2 evolution efficiencies with T5-3?T5-6 improved significantly with increasing sulfur content. This work highlights the significance of IL-assisted precursor route synthesis and the tuning of photocatalytic properties through the formation of solid solutions.

Electronic Properties of Copper(I) Thiocyanate (CuSCN)

With the emerging applications of copper(I) thiocyanate (CuSCN) as a transparent and solution-processable hole-transporting semiconductor in numerous opto/electronic devices, fundamental studies that cast light on the charge transport physics are essential as they provide insights critical for further materials and devices performance advancement. The aim of this article is to provide a comprehensive and up-to-date report of the electronic properties of CuSCN with key emphasis on the structure?property relationship. The article is divided into four parts. In the first section, recent works on density functional theory calculations of the electronic band structure of hexagonal beta-CuSCN are reviewed. Following this, various defects that may contribute to the conductivity of CuSCN are discussed, and newly predicted phases characterized by layered 2-dimensional-like structures are highlighted. Finally, a summary of recent studies on the band-tail states and hole transport mechanisms in solution-deposited, polycrystalline CuSCN layers is presented.

Subtle side chain effect of methyl substituent on the self-assembly of polypseudorotaxane complexes: Syntheses, structural diversity and photocatalytic properties

Cation-templated self-assembly of 1,n-bis(4-methylpyridine)alkane cations (n = 3-7) with CuSCN was studied and a series of new polymeric thiocyanate frameworks were obtained: {(bmpp)[Cu2Br2(SCN)2]}n (1), {(bmpt)[Cu2(SCN)4]}n (2), {(bmppt)[Cu2(SCN)4]}n (3), {(bmph)[Cu4(SCN)6]}n (4), {(bmphp)[Cu2(SCN)4]}n (5), (n = 3, bmpp; n = 4, bmpt; n = 5, bmppt; n = 6, bmph; n = 7, bmphp). The structures consist of 1-2D frameworks with the dications trapped within host network cavities. Compounds 1, 2, 3 and 5 possess the infinite two-dimensional polypseudorotaxane anion networks. Compound 4 has a novel 1D chain structure which looks like lotus root. The results demonstrate that the side chain of methyl substituent plays an important role in the fabrication of polypseudorotaxane structures. Furthermore, solid UV-Vis spectra, photoluminescence and photocatalytic properties at ambient temperature were also investigated.

Disorder-robust bands from anisotropic orbitals in a coordination polymer semiconductor

While the effects of structural disorder on the electronic properties of solids are poorly understood, it is widely accepted that spatially isotropic orbitals lead to robustness against disorder. In this paper, we use first-principles calculations to show that a cluster of occupied bands in the coordination polymer semiconductor beta-copper(I) thiocyanate undergo relatively little fluctuation in the presence of thermal disorder-a surprising finding given that these bands are composed of spatially anisotropic d-orbitals. Analysis with the tight-binding method and a stochastic network model suggests that the robustness of these bands to the thermal disorder can be traced to the way in which these orbitals are aligned with respect to each other. This special alignment causes strong inverse statistical correlations between orbital-orbital distances, making these bands robust to random fluctuations of these distances. As well as proving that disorder-robust electronic properties can be achieved even with anisotropic orbitals, our results provide a concrete example of when simple ‘averaging’ methods can be used to treat thermal disorder in electronic structure calculations.

Three pillared-layered inorganic-organic hybrid polymers with efficient luminescence

Three pillared-layered inorganic-organic hybrid polymers, namely, [Cu2(4,4?-Hbpt)(SCN)2]n (1), [Cd(4,4?-Hbpt)(SCN)2]n (2), and [Cd(4,4?-Hbpt)(SCN)2¡¤CH3CN]n (3) were synthesized via layer diffusion methods. In all three complexes, there exist 2-D neutral wave-like d10 metal thiocyanate layers (for 1, [Cu2(SCN)2]n, and for 2 and 3, [Cd(SCN)2]n) with (4, 4) topology, which are further connected by bidentate 4,4?-Hbpt ligands to form 3-D structures with the primitive cubic topology. The results of photoluminescence and thermogravimetric analyses indicate that the three complexes are good candidates as luminescent materials. This paper provides a strategy to synthesize a novel family of pillared-layered inorganic-organic hybrid polymers constructed with layered d10 metal thiocyanate layers and conjugated organic spacers at the molecular engineering level, as well as the discovery of new patterns of crystallization at the crystal engineering level.

Photoelectron spectra of gamma-substituted nickel(II) and copper(II) bis(acetylacetonates)

The electronic structures of Ni(II) and Cu(II) bis(acetylacetonates) and some of their gamma-substituted analogues (X = Cl, Me) are studied by photoelectron spectroscopy (PES). The vertical ionization energies of the compounds are determined, and the spectra are interpreted based on the trends of changes in the electronic structure and photoelectron spectra of acetylacetonates upon gamma-substitution. The suggested interpretation of the photoelectron spectra is confirmed by the quantum chemical INDO calculations of the electronic structure of the Cu(II) compounds.
