Special Issue Information

Dear Colleagues,

Electrocatalysis is an important branch of catalysis research; it is cross-disciplinary in nature and attracts the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. In recent decades, various electrocatalytic reactions, such as water splitting, oxygen reduction, carbon dioxide reduction, nitrogen reduction, alcohol oxidation, etc. have received a great deal of attention from the academic community, industrial researchers, as well as governments.

Noble metal-based catalysts have been considered the benchmarks for various electrocatalytic reactions due to the high activity. However, this is economically unfavorable due to their limited reserves and high cost for industrial use. To overcome this challenge, investigations of low-cost metal oxide catalysts with both satisfactory intrinsic activity and stability have attracted significant attention in recent years.

This Special Issue aims to cover the latest studies on metal oxide catalysts for electrocatalytic-related applications, providing a platform for the presentation of cutting-edge innovative research with application value and in-depth mechanistic studies.

It is our pleasure to invite you to submit a full paper, detailed review, or significant preliminary communication related to metal oxides electrocatalysis.

The development of high-entropy anodes, known for their excellent catalytic activity for water oxidation, can depress the energy consumption of hydrogen production by water electrolysis. However, the complex preparation methods and poor stability hindered their practical application. In this work, a one-step co-precipitation method has been modified to rapidly synthesize ultrathin high-entropy layered double hydroxide containing Ni, Co, Fe, Cr, Zn. Through the rational selection of metal elements, the stability of the optimized anode under Ampere-level current density has been significantly improved. Compared to NiFe-LDH, the active site leaching of high-entropy LDH is reduced by 42.7%, and as a result, it achieves a performance decay that is approximately eight times lower than that of NiFe-LDH. Experiment results show that the active sites in the high-entropy LDH can maintain a relatively low oxidation state both before and after activation, thus preventing material deactivation caused by excessive oxidation.
