In this paper, we present a systematic investigation of the photocatalytic H2 production over the Sr1−1.5xLaxWO4 (0 ≤ x ≤ 0.2) solid solutions. The doped La3+ ion in the crystal structure was identified by the Le Bail fit on the X-ray diffraction pattern of the as-prepared sample. The cell volume of the doped sample was linearly decreased by the augmentation of the La3+ ion. The morphology and composition of Sr0.82La0.12WO4 were observed by the transmission electron microscope, scanning electron microscope, and X-ray photoelectron spectroscopy. And then the loading of Cu, Ag, Au, Pt, Ni, and Ru as cocatalysts on sub-crystallite Sr0.82La0.12WO4 sample for H2 production was studied. The optimum H2 production rate is 309.7 μmol/h/g for 1.5 wt% Ru/Sr0.82La0.12WO4, which is 3.1 times than the undoped sample. And its apparent quantum yield is 0.44% at 365 (± 15) nm. All the photocatalysts recycled after the photocatalytic reactions show no degradation.
