수소 생산 반응을 위한 바이메탈릭 전이금속 질소화물의 최근 연구 동향

초록

Electrochemical water splitting combined with renewable energy sources is widely considered as a promising route for clean and efficient hydrogen production. For wide-spread application of water splitting system, development of economical and efficient non-precious electrocatalyst is required to replace typical precious metal catalysts in hydrogen evolution reactions (HER). Although transition metal nitrides (TMNs) are promising HER catalysts owing to the high electrical conductivity and unique electronic structure, monometallic nitrides still showed inferior activity than precious metal catalysts. Recently, to improve the HER activity of monometallic TMNs, much attention is paid to bimetallic TMNs, which are expected to show a synergy between two distinct metals. This review highlights the recent progress on the development of bimetallic TMNs and their HER performances.
