PROBLEM TO BE SOLVED: To provide a photocatalyst having a low toxicity and enabling a complete decomposition of water into hydrogen and oxygen, or a photocatalyst for decomposing organic matter having a high activity, and a photocatalyst containing a cerium oxide useful as a photocatalyst or the like of a photosynthesis reaction, as an active ingredient. SOLUTION: (2) A heterogeneous element selected from a group consisting of calcium, strontium, yttrium, and lanthanum is added to (1) the cerium oxide, and further, the photocatalyst for decomposing water and the organic matter is constituted by supporting a ruthenium oxide or platinum as (3) a promoter.
