Advances in electrochemical synthesis of ammonia
摘要
Abstract
Ammonia (NH3) is one of the most widely produced chemicals worldwide with a key role in the growth of global economy. Traditional ammonia synthesis by the Haber-Bosch process runs at high temperature and pressure with low hydrogen conversion, high energy consumption and severe environmental pollution. Electrochemical synthesis of ammonia has been immensely studied as it is operated at ambient temperature and pressure. The electrochemical synthesis has been improvedvia choosing electrolyte systems, preparing electrodes and electrocatalysts, and constructing highly efficient and stable electrochemical cells. This review summarized recent progress of electrochemical ammonia synthesis in five electrolyte systems including liquid electrolyte, proton conductor ceramic membrane, molten salts, a composite electrolyte of molten salts and ceramic membrane, and organic proton exchange membrane. Mechanism of electrochemical ammonia production, current technical status, major challenges and future directions were discussed.关键词
