多价MnOx/C电催化剂用于高效氮还原反应
Polyvalent MnOx/C Electrocatalyst for Highly Efficient Nitrogen Reduction Reaction
摘要
Abstract
NH3 plays an important role in human production and life , but the main way to produce NH 3 is still the high energy consumption and high pollution Haber-Bosch process.Electrocatalytic N2 reduction reaction (ENRR) is considered to be an effective alternative method , however highly efficient catalyst is still a challenging as a result of high bond energy of N(=)N.Here, we report an electrocatalyst of polyvalent MnO x/C which is designed via simple redox reaction for highly efficient production of ammonia ( with yield up to 7.8 μgNH3/( h· mgcat ) and Faradic efficiency (FE) up to 9.2％) from nitrogen reduction reaction (NRR).The high NRR performance of polyvalent MnOx/C mainly originates from a synergistic effect among different valence states ( Mn2+, Mn3+, Mn4+) of Mn for NRR.关键词
