Molten-salt synthesis of Cu–SrTiO3/TiO2 nanotube heterostructures for photocatalytic water splitting
A series of Cu-loaded SrTiO 3 /TiO 2 nanotube heterostructures were synthesized by a facile molten salts method and an impregnation-calcination method. Through adjusting the molar ratio of Sr/Ti, the photocatalytic performance of the samples changed regularly. When Sr/Ti = 0.2, the catalyst showed t...
