NOVELTY - A catalyst carrier comprises metal oxide and doped graphene. USE - Catalyst carrier for noble metal ceramic catalyst body (claimed). ADVANTAGE - The carrier increases active site of metal catalyst, is effective, and has increased photocatalytic activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for application of catalyst carrier for increasing photocatalytic activity of noble metal ceramic catalyst body which involves dissolving catalyst carrier in water and methyl alcohol mixed solution to obtain catalyst carrier solution having 0.1-10 mg/ml concentration in which volume ratio water:methanol is 1/3-3, preparing aqueous chloroplatinic acid solution having 1-100 mg/ml concentration and aqueous surfactant solution having 1-100 mg/ml concentration, injecting equal volume of aqueous chloroplatinic and surfactant solutions in catalyst carrier solution in which mass ratio chloroplatinic acid:catalyst carrier is 20-0.1, and light irradiating injected solution for 15-90 minutes. DESCRIPTION OF DRAWING(S) - The drawings show transmission electron microscopic images of catalyst carrier after loading.
