NOVELTY - Preparing photo-catalyst composite involves adding de-ionized water to graphene oxide to obtain the first graphene oxide solution. The glucose is added to the first graphene oxide solution to obtain second graphene solution. The 24-26 wt.% ammonia aqueous solution is added to the second graphene oxide solution to obtain third graphene solution. The third graphene solution is heated, centrifuged and washed with to obtain graphene suspension. The titanium tetrachloride solution, nickel nitrate hexahydrate, and urea are added to the graphene suspension. USE - Method for preparing photo-catalyst composite (claimed). ADVANTAGE - The method enables to prepare photo-catalyst composite in simple manner, has strong light absorbing ability, high photo-catalytic efficiency and stable performance.
