Electrolytic water technology based on transformable and amorphous liquid metal electrodes

Abstract

Hydrogen has important values in industrial manufacture, medical health care, and diverse energy application areas. Among the many possible approaches, convenient and safe hydrogen production from water electrolysis has always been a preferred in situ hydrogen supply technology. So far, many of the electrodes thus involved are based on rigid metals or conductive items which may encounter inconvenience or insufficiency sometimes. To achieve targeted release of hydrogen, appropriate administration of suitable flexible hydrogen evolution electrodes is the key. In recent years, gallium-based liquid metals have emerged in the field of flexible and biological electrodes. Starting from this point, liquid metal is proposed here as a transformable amorphous electrode for hydrogen evolution in electrolytic water which may help mold new conceptual electrolysis and energy utilization ways.

Perspectives on Mo-Based Electrocatalysts for the Hydrogen Evolution Reaction: A Comprehensive Review

“…Recently, various metallic compounds have been explored as catalysts for HER, such as Fe, Co, and Ni. − Among these catalysts, molybdenum-based materials stand out as promising candidates due to their lower cost, richness in natural resources, and better catalytic stability (as depicted in Figure ). Nevertheless, the catalytic performance of Mo-based compounds does not yet meet the requirements for industrial applications, mainly due to their low active sites and poor electrical conductivity.…”
