英文摘要：
To clarify the nature of different photocatalytic activities between niobate and tantalate, a comparative study of the water splitting into H2 over strontium niobate and tantalate was performed. These isostructural photocatalysts were prepared by a facile and simple hydrothermal reaction and characterized by powder X-ray diffraction （XRD）, N2-sorption, UV-Vis diffuse reflectance spectra （UV-Vis DRS）, and transmission electron microscopy （TEM）. The effects of crystal structure, Brunauer-Emmett-Teller （BET） surface area, photoabsorption performance, morphology, and electronic structure are discussed.
