Recent progress on rational design of catalysts for fermentative hydrogen production

Abstract

The increasingly severe energy crisis has strengthened the determination to develop environmentally friendly energy. And hydrogen has emerged as a candidate for clean energy. Among many hydrogen generation methods, biohydrogen stands out due to its environmental sustainability, simple operating environment, and cost advantages. This review focuses on the rational design of catalysts for fermentative hydrogen production. The principles of microbial dark fermentation and photo‐fermentation are elucidated exhaustively. Various strategies to increase the efficiency of fermentative hydrogen production are summarized, and some recent representative works from microbial dark fermentation and photo‐fermentation are described. Meanwhile, perspectives and discussions on the rational design of catalysts for fermentative hydrogen production are provided.

Electrocatalytic C–N coupling for urea synthesis: a critical review

“…[32][33][34][35][36] The ideal catalyst should have exceptional capabilities for reactant capture, energy barrier management, bond cleavage, and coupling of intermediates. 37,38 Currently, the major electrocatalytic systems for urea synthesis apply metal-Fig. 1 The progress of C-N coupling reaction for electrocatalytic urea synthesis.…”

“…32–36 The ideal catalyst should have exceptional capabilities for reactant capture, energy barrier management, bond cleavage, and coupling of intermediates. 37,38 Currently, the major electrocatalytic systems for urea synthesis apply metal-based catalysts including copper, gold, indium, etc (Table 1). Aiming to enhance catalytic performances, the optimization of electronic structure, coordination environment, carrier properties, and interfacial interactions are key factors to be solved.…”

Solar‐Driven Hydrogen Evolution from Value‐Added Waste Treatment

“…Considering that the hydrolyzed molecules have similar structure with raw biomass, some works also investigated photooxidation of biomass derivatives as an alternative for a better understanding of the reaction process. Among them, glucose, [56,[68][69][70][71] xylose, [72] arabinose, [73] glycerol, [74] lactic acid, [75] ascorbic acid, [76] HMF [77][78][79][80] and etc. have been widely reported.…”

Recent advances in carbon-supported non-precious metal single-atom catalysts for energy conversion electrocatalysis

“…The rapid consumption of traditional fossil fuels has led to a global energy crisis and environmental challenges, which has made the research on renewable energy conversion systems, such as fuel cells, and electrolyzers, becoming the current research hotspot [1][2][3][4][5][6][7][8][9]. Electrocatalysts play critical roles in the energy conversion reactions like carbon dioxide reduction reaction (CO 2 RR) [10,11], hydrogen evolution reaction (HER) [12,13], oxygen evolution reaction (OER) [14][15][16], oxygen reduction reaction (ORR) [17][18][19][20], and nitrogen reduction reaction (NRR) [21][22][23].…”
