چکیده
|
Crystallized pure sno2 powders were prepared by the sol-gel process, andwere used as photocatalyst for the degradation of phenol under uv light at ph 6.5 and atemperature of 20c. the physical properties of photocatalyst were characterized by x-raydi raction, scanning electron microscopy, nitrogen adsorption-desorption and ultravioletvisibledi use reectance spectroscopy. the inuences of di erent operating variables, suchas the ph, the photocatalyst loading, and the initial concentration of phenol, were studiedto improve the eciency of phenol degradation
