摘要: Abstract Bi 3 SbO 7 was synthesized by a solid state reaction method and the as-synthesized powder characterized X-ray diffraction (XRD) UV–vis diffuse reflectance spectrum. The photocatalytic activity of evaluated means degradation methyl orange; effects photocatalyst concentration, pH wavelength irradiation upon performance were investigated. character discussed in terms band structure crystal structure. results obtained reveal that has an intrinsic optical gap 2.71 eV can photocatalytically respond to light upto ∼600 nm. Generally, shows better activities than BiVO 4 under both UV visible because lower packing factor correspondingly higher structural openness .
