Article Synopsis
- * Two crystal phases of BiO (αBiO and βBiO) were synthesized and analyzed, with βBiO demonstrating superior N adsorption capabilities and a lower energy barrier for critical NRR steps (0.51 eV).
- * The introduction of NaBH to the BiO catalysts enhanced their performance by increasing active sites and suppressing HER, resulting in the optimized βBiO-0.6 catalyst achieving a notable NH yield of 51.36 μg h mg and a Faradaic efficiency of 38.67%.
Electrocatalytic nitrogen reduction reaction (NRR) has attracted much attention as a sustainable ammonia production technology, but it needs further exploration due to its slow kinetics and the existence of competitive side reactions. In this research, xAu/MIL-101(Fe) catalysts were obtained by loading gold nanoparticles (Au NPs) onto MIL-101(Fe) using a one-step reduction strategy. Herein, MIL-101(Fe), with high specific surface area and strong N adsorption capacity, is used as a support to disperse Au NPs to increase the electrochemical active surface area.
