Abstract
Calcination of a cerium-S-phenylene-O-holmium-O-phenylene-S hybrid copolymer under a vacuum gave cerium oxide–carbon cluster–holmium oxide composite material. The material calcined at 600 °C loaded with Pt particles could decompose water to H2 and O2 with a H2/O2 ratio of 2 under visible light irradiation. ESR spectral examinations of the calcined materials revealed the possibility of a two-step electron transfer in the process of CeO2 → carbon cluster → Ho2O3 → Pt with an oxidation site at CeO2 particles and a reduction site at Pt particles.
