Overall hydrazine splitting (OHzS) is a promising alternative for overall water splitting (OWS) towards hydrogen production due to the anodic hydrazine oxidation reaction (HzOR) involving less electrons and faster kinetics than oxygen evolution reaction (OER). However, it still remains a challenge to synthesis bifunctional electrocatalyst for hydrogen evolution reaction (HER) and HzOR with low overpotentials. Herein, we report two-dimensional multifunctional layered double hydroxide derived from metal-organic framework sheet precursor supported by nanoporous gold with high porosity and demonstrate its dual appealing activities for both HER and HzOR. Notably, the OHzS cell only needs a cell voltage of 0.984 V to deliver 10 mA·cm-2, which is far more superior than that of the OWS system (1.849 V). Besides, the electrolysis cell could stably operate for more than 130 h. (Xicheng Gao, Jianqiang Bi, Linjie Meng, Lulin Xie, Chen Liu, Front. Chem. Sci. Eng. 2024, 18(1): 6)[展开] ...
