A high entropy metallic-high entropy nonmetallic community as a high performance electrocatalyst for the oxygen evolution reaction and oxygen reduction reaction.

ABSTRACT: The multi-element synergism in high-entropy materials (HEMs) provides great opportunities as multi-functional catalysts or for the promotion of tandem reactions. Herein, a strategy that utilizes a high entropy precursor is proposed to realize the formation of a unique high entropy metallic-high entropy non-metallic community (HEM-HENMC). Aminotriazole acts as a "bonding agent" for the high entropy precursor, and not only binds the five metals Cr, Mn, Fe, Co and Ni together, but also introduces nitrogen and carbon in situ. After simultaneous phosphorization and vulcanization and surface oxidation, the unique HEM-HENMC containing five metals (Cr, Mn, Fe, Co and Ni) and five non-metals (C, N, O, P and S) was successfully prepared. The synergistic effect of the various non-metal and met
