Function of triazenido compound for electrocatalytic hydrogen production catalyzed by platinum complex

Abstract

A new type of electrocatalyst based on a triazenido-platinum complex, Pt(PPh₃)₂(L)Cl (1), is prepared by the reaction of 1-[(2-methoxy) benzene]-3-[2-pyridine] triazene (HL) and Pt(PPh₃)₂Cl₂ in the presence of triethylamine. Electrochemical studies indicate that HL, Pt(PPh₃)₂Cl₂ and 1 can catalyze hydrogen evolution from acetic acid or a neutral buffer. To show triazenido ligand, HL, plays a role in determining the catalytic activities of the platinum complex, we systematically study the electrocatalytic activities of HL, Pt(PPh₃)₂Cl₂ and Pt(PPh₃)₂(L)Cl and provide a possible catalytic mechanism for hydrogen generation catalyzed by 1.
