A novel high-entropy sulfide (ZnCoMnFeAlMg)9S8 as a low potential and long life electrocatalyst for overall water splitting in experiments and DFT analysis

Shun Li, Likai Tong, Zhijian Peng, Bo Zhang, Xiuli Fu

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
