摘要

介绍了N₂还原合成NH₃催化剂的2种催化反应机理：缔合途径和解离途径。综述了近年来电催化剂（贵金属、过渡金属和非金属）和光催化剂最新研究进展，最后对该新型领域催化剂的设计进行了展望。

Abstract

Reaction mechanisms of two catalytic reaction pathways (associative pathway and dissociative pathway) for reduction of N₂ to NH₃ are introduced.The latest research progress in electrocatalysts (noble metals,transition metals and nonmetals) and photocatalysts for nitrogen to ammonia under ambient conditions is reviewed.The design of the catalyst in this new field is prospected.
