Disclosed are a P—N heterojunction composite material supported on the surface of nickel foam, a preparation method therefor and the application thereof. The composite material is a supported catalyst which can be used to remove pollutants in water by means of photoelectrocatalysis. The method comprises firstly modifying, by means of a hydrothermal method, a layered nickel-iron bimetallic hydroxide nanosheet on the surface of clean nickel foam, and then modifying cobalt oxide nanowires on the surface of the layered nickel-iron bimetallic hydroxide nanosheet by means of a mixed solvent-thermal method, so as to obtain a P—N heterojunction catalyst composite material supported on the surface of nickel foam (Ni foam@NiFe-LDH/Co.sub.3O.sub.4). The composite material has a good response to visible light, which can greatly enhance the absorption and utilization of light, and is further beneficial to enhance the performance of the catalyst.

The invention concerns a method for preparing a mixture containing cyclohexanol and cyclohexanone, comprising the step of hydrogenating cyclohexyl hydroperoxide in cyclohexane in the presence of a Raney nickel catalyst to give cyclohexanol and cyclohexanone.
