Water electrolysis is relatively an environmentally friendly hydrogen production technology, but due to the slow transfer of four electrons in anodic oxidation reaction, it needs a theoretical voltage up 1.23 V. Therefore, this experiment, series transition metal oxides, ACo2O4 (A = Fe, Cu, Zn, Ni), was synthesized on Ni foam current collectors by hydrothermal and calcination method, material applied urea produce hydrogen. What noteworthy that CuCo2O4 electrode has unique flower-like nanoneedle structure, larger electrochemical active area, more reactive sites, faster charge rate. In 1.0 M KOH 0.5 solution, provides potential only 1.268 V at density 10 mA cm-2 during reaction (UOR), while with same density, oxygen evolution (OER) required provide 1.53 V, indicating UOR can effectively replace OER. Density functional theory calculations show exhibits Gibbs free energy closest zero, thus promoting electrochemistry performance electrode. cell composed CuCo2O4//CuCo2O4, be achieved providing 1.509 This work offers novel scheme for reducing consumption OER improving catalytic UOR.

Abstract Bismuth vanadate (BiVO 4 ), as a promising photoanode for photoelectrochemical (PEC) water splitting, suffers from poor charge separation efficiency and light absorption efficiency. Herein, iron oxychloride (FeOCl) is introduced novel cocatalyst simply grafted on BiVO to construct an integrated photoanode, enhancing PEC performance. The optimized FeOCl/BiVO exhibits superior photocurrent density value of 5.23 mA cm −2 at 1.23 V versus reversible hydrogen electrode (RHE) under AM 1.5G illuminations. From experimental analysis, such high performance ascribed the unique properties FeOCl, facilitating transport, increasing efficiency, promoting oxidation kinetics. Density functional theory calculations further confirm that FeOCl optimizes Gibbs free energy H O‐containing intermediates (OOH * ) during processes, boosting catalytic kinetics splitting. This work presents catalyst constructing efficient water‐splitting photoanodes.
