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 indium 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 indium 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.

The invention concerns a composition comprising a mixture of zinc sulphide (ZnS) and molybdenum sulphide (MoS), in which the Mo/Zn molar ratio is in the range 0.01 to 1.9. The invention also pertains to a process for its preparation as well as to its application in photocatalysis and more particularly to its application in photocatalysis for the production of dihydrogen from water (HO) and/or hydrogen sulphide (HS) and/or any other source of protons in the presence of a source emitting in the ultraviolet and/or visible spectrum.
