The influence of glycine, glycerine, ethylene glycol and citric acid fuel and their ratio to NO3 - on formation and dispersity of Bi2WO6 nanoparticles prepared by combustion synthesis has been studied. The pure crystalline Bi2WO6 with specific surface area 24.8 m2/g and crystallite size of 28 nm was obtained by using glycerine as fuel at its ratio to NO3 - of 0.67. The photocatalytic activity of the prepared Bi2WO6 in degradation of methylene blue depended on its specific surface area of samples and solution pH.
