Photocatalytic reduction of CO2 and H2O to CO and H2 with a cobalt chlorin complex adsorbed on multi-walled carbon nanotubes

Abstract

The photocatalytic reduction of CO₂ and H₂O with triethylamine occurred efficiently using a cobalt(II) chlorin complex adsorbed on multi-walled carbon nanotubes as a CO₂ reduction catalyst and [Ru^II(Me₂phen)₃]²⁺ (Me₂phen = 4,7-dimethyl-1,10-phenanthroline) as a photocatalyst to yield CO and H₂ with a ratio of 2.4 : 1 and a high turnover number of 710.
