Vanadium doped titania (TiO 2 ) nanoparticles was synthesiz ed by sol gel method. On this basis of using ultrasonic impregnation method by use of ethyl silicate and citric acid on the catalysts surface for further modification to prepare eth er compound wrapped strong reducible photocatalyst. By using of 100 mg/L po tassium dichromate and 30 mg/L methyl orange as degradation model, studied Si citric acid V co modified TiO2 catalyst redox property. Experimental results indicate that Si citric acid V co modified TiO 2 catalyst particle size is the smallest nanometer sphe re and have reunion phenomenon. On the surface of catalyst is introduced into the hole scavengers is helpful to improve the reduction of the catalyst while it is harmful to improve the oxidation ability. Si citric acid-V co-modified TiO2 photocatalytic per formance relatively stable..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
