Application of Non-Precious Transition Metal Catalyst in Electrocatalytic Nitrogen Synthesis of Ammonia
As an important chemical product and chemical raw material,ammonia is widely used in industry,agriculture,medicine and other industries,and plays an irreplaceable role in global economic development.At present,industrial ammonia synthesis mainly uses the traditional Haber-Bosch process,which consumes a lot of fossil energy and has a relatively low equilibrium conversion rate.Electrocatalytic nitrogen reduction of ammonia synthesis can convert N2and H2O into NH3at normal temperature and pressure,and it is easy to operate and easy to obtain raw materials,which has become an important research direction in the scientific research field.Among them,non-precious metal transition metal-based oxides,nitrides,sulfides,bimetal catalysts and heteroatom-based catalysts represented by transition metals in zone d showed good catalytic performance.This paper focuses on the recent progress of electrocatalytic ammonia production by transition metal-based electrocatalytic nitrogen reduction reaction(E-NRR),including its challenges,reaction mechanism,and different materials of E-NRR catalysts,and focuses on the structure-performance relationship.The strategies and prospects for improving the performance of E-NRR were introduced from the aspects of synthesis scheme,structure modification,activity,selective enhancement and reaction mechanism 。
