PHOTOCATALYST AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a photocatalyst which has a high catalytic activity and long service life, is free from toxicity and can directly use visible light in photocatalytic reaction and which is especially useful for generating hydrogen, and to provide a method of producing the same. SOLUTION: The photocatalyst contains cadmium sulfide and has a capsule structure. Platinum is supported in the photocatalyst. The photocatalyst is obtained by bubbling gaseous H2S in a liquid to which cadmium oxide particles are added. COPYRIGHT: (C)2003,JPO
