Abstract

See full text

The invention relates to a composition that contains a first semiconductor SC1, particles that comprise one or more element(s) M in the metal state selected from among an element of groups IVB, VB, VIB, VIIB, VIIIB, IB, IIB, IIIA, IVA and VA of the periodic table, and a second semiconductor SC2 that comprises cerium oxide, with said first semiconductor SC1 being in direct contact with said particles that comprise one or more element(s) M in the metal state, with said particles being in direct contact with said second semiconductor SC2 that comprises cerium oxide in such a way that the second semiconductor SC2 covers at least 50% of the surfaces of the particles that comprise one or more element(s) M in the metal state. The invention also relates to its preparation method as well as its application of photocatalysis.
