Published: Oct. 27, 2021

Abstract Electrochemical water splitting powered by renewable energy sources has been considered as an attractive hydrogen generation technology with high‐purity product and zero carbon emission. However, the efficient realization of large‐scale is severely hampered sluggish hydrogen/oxygen evolution reaction (HER/OER). As important class functional materials, complex hollow electrocatalysts provide promising solutions to accelerate HER/OER kinetics owing their advantageous features, such abundant exposed active sites, increased contact area between catalysts electrolyte, shortened mass/charge transport length. Herein, recent advances in development outstanding performances are summarized. Beginning introduction mechanisms design principles, achievements engineering highlighted focus on structural modulation, composition control, electrocatalytic evaluation. Finally, some present challenges future perspectives for advanced toward further discussed.

The urea oxidation reaction (UOR) is considered as an alternative to the oxygen evolution for high-efficiency hydrogen production. However, molecule relatively complex, containing both electron-donating amino (−NH2) and electron-withdrawing carbonyl (C═O) groups, understanding influence of different functional groups on adsorption behavior conducive rational design preparation high-performance UOR catalysts. Herein, we report a simple synthesis Ni3N/Mo2N heterostructure systematic investigation urea-assisted electrolytic Both temperature-programmed desorption theoretical calculations decipher that −NH2 C═O are more easily adsorbed Ni3N Mo2N, respectively. Meanwhile, could combine enhance advantages individual components, optimizing urea. Besides, this also beneficial improving performance. As expected, in two-electrode water electrolyzer utilizing bifunctional catalysts, production can readily occur at evidently lower voltage (1.36 V@10 mA cm–2), which much than traditional electrolysis, well 7 times higher rate achieved.
