Carbon black supported manganese phthalocyanine: Efficient electrocatalyst for nitrogen reduction to ammonia

Engineering Reports, Journal Year: 2023, Volume and Issue: 6(1)

Published: June 20, 2023

Abstract Ammonia (NH 3 ) is regarded as a renewable energy source well an important molecule for agricultural applications. The energy‐intensive Haber‐Bosch method produces large amounts of CO 2 gas during ammonia production. As alternative, there has recently been much interest in the electrocatalytic production NH via electrochemical nitrogen reduction reaction (ENRR) process utilizing under ambient condition. Herein, we report conducting carbon–supported manganese phthalocyanine electrocatalyst efficient ENRR MnPc exhibited activity with rate 61.8 μg h −1 mg cat Faradaic efficiency (FE) 31.3% @–0.4 V vs. RHE, respectively, condition 0.1 M HCl solution whereas MnPc/C enhanced productivity yield 127.7 FE 35.3% respectively. reliability N origin formation demonstrated by 1 H‐NMR experiments and multiple control analysis. These results open way further study carbon‐supported transition‐metal compounds fixation to .

Abstract Efficient and sustainable energy development is a powerful tool for addressing the environmental crises. Single‐atom catalysts (SACs) have received high attention their extremely atom utilization efficiency excellent catalytic activity, broad application prospects in chemical production. M‐N 4 an active center model with clear but its properties such as selectivity, durability need to be further improved. Adjustment of coordination environment central metal by incorporating heteroatoms (e.g., sulfur) effective feasible modification method. This paper describes precise synthetic methods introducing sulfur atoms into controlling whether they are directly coordinated form specific configuration, sulfur‐doped carbon‐based single‐atom electrocatalytic reactions ORR, CO 2 RR, HER, OER, other reaction systematically reviewed. Meanwhile, effect tuning electronic structure ligand configuration parameters due doped improvement performance introduced combining different characterization testing methods. Finally, several opinions on SACs put forward.
