Photocatalytic reduction of CO2 and H2O to CO and H-2 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(Me(2)phen)(3)](2+) (Me(2)phen = 4,7-dimethyl-1,10-phenanthroline) as a photocatalyst to yield CO and H-2 with a ratio of 2.4 : 1 and a high turnover number of 710.
