NOVELTY - Preparing nano- rod ferric oxide/niobium dioxide/graphene oxide (Fe2O3/NbO2/GO) composite material involves mixing ferric chloride, niobium chloride and urea to prepare low eutectic solvent; roasting the low eutectic solvent to obtain the (Fe2O3/NbO2/GO) composite material. USE - Method for preparing nano- rod ferric oxide/niobium dioxide/graphene oxide composite material which is used in preparing hydrogen by decomposing photo-catalytic water (claimed). ADVANTAGE - The method has simple operation, low preparation cost, easy industrial production, has regular shape and good crystal form, has excellent photoelectric catalytic performance which can be applied to the light catalytic water decomposition to prepare hydrogen. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of the Fe2O3/NbO2/GO composite material used in preparing hydrogen by decomposing photo-catalytic water.
