Photocatalyst

Abstract

A photocatalyst is described that is suitable for converting molecular nitrogen into ammonia. The photocatalyst comprises a layered base material comprising 1 to 100 layers, the layered base material being selected from the group consisting of molybdenum disulfide, tungsten disulfide, molybdenum telluride, tungsten telluride, molybdenum selenide and tungsten selenide, a layered base material comprising 1 to 100 layers, the layered base material being selected from the group consisting of molybdenum disulfide, tungsten disulfide, molybdenum telluride, tungsten telluride, molybdenum selenide and tungsten selenide, and 0.1-10.0% by weight, relative to the weight of the base material, of one or more Group VI, VII, VIII, IX or X transition metals. The photocatalyst can further comprise 0.1-50.0% by weight, relative to the weight of the base material, of one or more semiconductor materials having an average particle size of 0.5-50.0 nm. The photocatalyst exhibits high catalytic efficiency without the need for high temperature and pressure. Also described is a process for the preparation of the photocatalyst, as well as uses of the photocatalyst for converting molecular nitrogen into ammonia.
