Abstract
A composite photocatalyst, a method of producing said composite photocatalyst, a method of degrading an organic pollutant using the composite photocatalyst, and a method of producing hydrogen using the composite photocatalyst. The composite photocatalyst includes graphene, tungsten oxide, a metal boride, and a metal hydroxide. The photocatalyst is capable of degrading an organic pollutant when exposed to light. The photocatalyst is also capable of producing hydrogen from water when exposed to light under suitable conditions.
