Porous high-entropy alloys (HEAs) have emerged as promising electrocatalysts for water-splitting reactions, owing to their rich dissimilar active sites, elemental diversity, and multiple functionalities. The rational design of HEAs attracted great interest in improving current performance, so it is essential provide timely updates on this field. This review emphasizes the preparation methods po...

Two A2B cobalt triaryl corroles bearing ester (1) or carboxylic acid group (2) at the 10-para-phenyl were prepared and used as homogeneous electrocatalysts for hydrogen evolution reaction (HER) with acetic water proton sources. CV results revealed HER underwent two routes [CoIII–H]– (EECC pathway) [CoII–H]2– (ECEC intermediates low concentration. While mainly went through ECEC route high The tu...

The controllable preparation of Two-dimensional transition metal chalcogenides (TMDCs) is very important. However, the uncontrollable growth SnS 2 by chemical vapor deposition (CVD) and unsatisfactory performance hydrogen evolution reaction (HER) based on have hindered its applications.

Combinatorial synthesis and screening for discovery of electrocatalysts has received increasing attention, particularly for energy-related technologies. High-throughput discovery strategies typically employ a fast, reliable initial screening technique that is able to identify active catalyst composition regions. Traditional electrochemical characterization via current-voltage measurements is in...

Sustainable and highly efficient non-noble metal catalysts could facilitate the realization of closed-loop carbon-neutral hydrogen (H2) economy via low-cost electrocatalytic (EC) or photocatalytic (PC) H2 evolution reaction (HER) from water. Herein, molybdenum carbide (MoC) quantum dots onto N-doped porous carbon are in situ synthesized immobilized, resulting a bifunctional catalyst MoC@NC. Den...

To enable a future society based on sun and wind energy, transforming electricity into chemical energy in the form of fuels is crucial. This transformation can be achieved an electrolyzer performing water splitting, where at anode, oxidized to oxygen—oxygen evolution reaction (OER)—to produce protons electrons that combined cathode hydrogen—hydrogen (HER). While hydrogen desired fuel, obtained ...

It remains a challenge to develop efficient electrocatalysts in neutral media for hydrogen evolution reaction (HER) due the sluggish kinetics and switch of rate determining step.
