In our work, a Cu9S5/Fe2O3 composite with nanosphere morphol. is prepared by an efficient one-pot solvothermal selective sulfurization. The structure investigation confirms that there is uneven charge distribution at the interfaces of Cu9S5 and Fe2O3. Furthermore, the corresponding electrochem. measurements reveal the detailed redox kinetics process about Cu2+/Cu+, Fe3+/Fe2+, and (S2)–/S2-. When the obtained Cu9S5/Fe2O3 composite is used as a neg. electrode, it exhibits a high specific capacity (348.2 mA h g-1 at 1 A g-1) with good rate capability. Moreover, a hybrid capacitor (HCP) assembled with Cu9S5/Fe2O3 as neg. and Ni-Co hydroxide/Cu(OH)2/CF as pos. electrodes, resp., shows a high energy d. with a corresponding high power d. (64.54 W h kg-1 at 757.81 W kg-1) and a high specific capacitance (47 mA h g-1 at 1 A g-1) with a capacity retention of 45.68% (21.5 mA h g-1) even at 20 A g-1 in a solid-state gel electrolyte. Thus, a facial fabricated anode material with outstanding electrochem. properties for HCPs is provided. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Electric Literature of CuH2O2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. It is clear from the impact copper catalysis has had on organic synthesis that copper should be considered a first line catalyst for many organic reactions.Electric Literature of CuH2O2
