摘要：A ternary composite photocatalyst system was prepared in a simple impregnation pyrolysis-process. In the photocatalyst system, multiwalled carbon nanotubes (MWNTs) acted as a catalyst and carrier, CuO and Cr2O3 acted as a co-catalyst and/or charge transferring site, and eosin Y acted as a sensitizer. Under visible light irradiation, activity of hydrogen evolution over the system (CuO/Cr2O3-MWNTs-eosin Y) was higher than that of CuO or Cr2O3 loaded MWNTs-eosin Y. It was demonstrated that simultaneous loading of CuO and Cr2O3 was vital to achieve the high activity. (C) 2014 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
