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.
