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.

Abstract Exploring advanced technologies to efficiently produce green hydrogen energy is imperative alleviate the crisis and environmental pollution. Conventional overall water electrolysis (OWE) has been regarded as a promising approach for effective H 2 production, however, it largely restricted by sluggish kinetics of anodic oxygen evolution reaction (OER). Coupling kinetically favorable reactions, such biomass‐derived compound oxidation pollutant degradation, with (HER) in hybrid (HWE), can not only solve biomass recycling emission problems but also save cost clean generation. Hence, various earth‐abundant electrocatalysts have developed catalyze those yet some tedious preparation unsatisfactory performance still exist. Given gap between research practical applications, this review summarizes recent progress diverse alternative reactions over last five years together their application HWE systems. An in‐depth understanding different mechanisms assessments toward discussed further enhance efficiency. The advantages, differences, critical issues systems are thoroughly well, providing new avenue low‐voltage production from renewable resources waste products.

Abstract Many biomass intermediates are polyols and selectively oxidizing only a primary or secondary alcohol group is beneficial for the valorization of these intermediates. For example, production 1,3-dihydroxyacetone, highly valuable oxidation product glycerol, requires selective oxidation. However, challenging due to its steric disadvantage. This study demonstrates that NiOOH, which oxidizes alcohols via two dehydrogenation mechanisms, hydrogen atom transfer hydride transfer, can convert glycerol 1,3-dihydroxyacetone with high selectivity when conditions controlled promote favoring rational achieved by enabling one desired pathway, without requiring alteration catalyst composition, how comprehensive mechanistic understanding enable predictive control over selectivity.
