Summary
This technique led to the successful synthesis of a 3D advanced material, Janus TMD. It applies emerging electrochemical NRR, achieving high selectivityFaradaic efficiency(FE) in ammonia conversion. The surface modification can be conducted using a plasma-assisted-seneizaion process, for which JTMDs were successfully obtained. The NRR behaviors were carried out using a potentiostat, resulting in the production of ammonia. spectrophotometer revealed a FE of up to 35.24.
Scientific Breakthrough
Electrochemical nitrogen reduction (NRR) has been a promising catalytic technology in recent years. Transition metal chalcogenides have been identified as suitable alternatives to precious metals. Our technique achieved three breakthroughs: direct deposition of the material on substrates to create the Janus TMDanalysis of energy changes during nitrogen conversion. Our team successfully synthesized 3D Janus WSeS/WSe2 nanowallsachieved a high Faradaic efficiency of 35.24  in NRR.
