摘要: Abstract Bismuth titanate nanoparticles were prepared by the anodic spark conversion route and effects of electrolyte’s constituents on electrochemical process studied. The experimental results showed that oxidation initiate bismuth to trioxide, which was further transformed into titanate. By diversifying amount NaOH H2O2 in electrolyte, phase formation, optical property photocatalytic ability titanates can be well-manipulated. Pure selinite-type Bi12TiO20 with size ca. 10 nm an electrolyte containing 0.8 M 0.4 M H2O2, exhibiting better UV–vis adsorption higher activity compared bulk one.
