Low temperature plasma-assisted synthesis and modification of water splitting electrocatalysts

Abstract

With the emerging climate and environmental problems, it is necessary to develop renewable energy technologies to alleviate the energy crisis. As one of the most promising technologies for hydrogen production, electrocatalytic water splitting has received extensive research attention in recent years, with efficient electrocatalysts as the key to realizing large-scale hydrogen production. After decades of development, non-noble metal-based materials have been widely studied in the fabrication of water splitting catalysts, while these materials still need to be improved compared to commercial noble metal catalysts. Among the many existing electrocatalyst modification strategies, low temperature plasma technology stands out due to the low energy consumption, high efficiency, and low chemical waste generation. Recent advances in the development and application of low temperature plasma technology in the synthesis and modification of electrocatalytic materials for water electrolysis is highlighted. It is expected to provide reference for the design and research of electrode materials in electrocatalytic water splitting with plasma-assisted technologies.
