| description | The invention discloses a SrTiO3/graphene composite catalyst for photocatalytically decomposing water as well as a preparation method and application thereof. The SrTiO3/graphene composite catalyst is prepared from SrTiO3 and graphene, wherein the SrTiO3 is loaded on the surface of the graphene. The preparation method of the catalyst comprises the following steps: firstly, adding tetrabutyl titanate into a graphene oxide dispersion solution; adding glacial acetic acid, and stirring and dissolving to obtain a solution A; weighing strontium nitrate and adding into de-ionized water, and stirring and dissolving to obtain a solution B; dropwise adding the solution B into the solution A and stirring uniformly; continually carrying out ultrasonic dispersion to form homogenized sol; adjusting the pH value to 13-14; and transferring the homogenized sol into a high-pressure reaction kettle, carrying out high-temperature treatment, and then cooling to obtain the SrTiO3/graphene composite catalyst. The SrTiO3/graphene co |
