Abstract
- A water-soluble polypyridine copper complex Cu(dpp)(ClO 4 ) 2 ( 1 , dpp = 2,9-di(pyridin-2-yl)-1,10-Phenanthroline) enables to electrocatalyze H 2 generation from neutral phosphate buffer solution at a relatively low overpotential of 520 mV vs. SHE. Sustained proton reduction catalysis occurs at glassy carbon electrode at −1.4 V vs. SHE for 2 h to give H 2 with TONs of 734 mol H 2 (mol catalyst) −1 cm −2 and 95% Faradaic yield. CVs, UV–Vis spectra, SEM, EDX and Tyndall analysis reveals that 1 has the desired stability and functions as a molecular electrocatalyst under the conditions. Due to the relatively low overpotential and high stability, light-driven hydrogen production based on 1 were also carried out with a TONs of 6 mol H 2 (mol catalyst) −1 in an aqueous solution.
