Improvement of photocatalytic activity and product selectivity by cadmium metal deposited in situ on suspended cadmium(II) sulfide particles

Article abstract of DOI:10.1246/cl.1995.803

Effect of annealing of commercial crystalline CdS powders on their photocatalytic activity and product selectivity was investigated for stereoselective diamino-N-cyclization of 2,6-diaminopimelic acid operated in deaerated aqueous solution.Surface analyses revealed the formation of sulfur vacancy, which promotes the photoinduced cadmium metal (Cd0) deposition.The Cd⁰, detected by reduction of methylviologen, may act as reduction site for photoexcited electrons.
