- Abstract
Electrocatalytic nitrogen reduction (ENRR) under mild conditions is an environmentally friendly nitrogen fixation strategy, which is expected to replace the Haber - Bosch process with harsh conditions, high energy consumption and environmental pollution. The development of high-performance electrocatalytic catalysts is the key to solve the problems of the difficulty in dissociation of the N=N triple bond and the difficulty in adsorption of nitrogen. Tn this paper, we prepared non-noble metal nanoporous FeNbMoP alloy catalyst with self-supporting structure by electrochemical dealloying method and applied it to catalyze ENRR. The addition of nano-porous structure and non-metal lie element and transition metal Nb element improves the reaction activity. and the catalyst after optimization has the ammonia yield of 23.3/.tg h-1 cm-2. This study provides a new direction for the subsequent synthesis of high-performance ENRR catalysts.
