Enhancing the photocatalytic hydrogen production performance of SrTiO3 by coating with a hydrophilic poloxamer

•P123@SrTiO3 shows high efficiency of photocatalytic hydrogen reduction performance, which is 31 times of SrTiO3.•The P123@SrTiO3 heterojunction was synthesized by one-step solvothermal method.•The hydrophilic heterojunction greatly improves the surface conductivity and inhibits the recombination of photogenerated carriers.
