Abstract


In this paper, natural zeolite is tetrabutyl titanate , anhydrous ethanol and glacial acetic acid as the raw material , the use of the sol - gel method , the prepared zeolite nano titanium dioxide , zeolite doped nano-titanium dioxide photocatalytic material , the material photocatalytic degradation performance of methyl orange . In order to explore the impact of different factors photocatalytic efficiency , design and orthogonal experiment , and ultimately determine the optimal conditions , namely ethanol : tetrabutyl titanate is : glacial acetic acid volume ratio of 30 ml : 25 ml : 15 ml zeolite particle size of 800 mesh , calcination temperature of 300 ° C , the amount of glacial acetic acid added 15 ml . Test and characterization testing of Fe 3 < / sup> Zn 2 N and La 3 doping test and La < / sup>, Fe 3 co- doping test . The results show that different types, different addition amount of ion photocatalytic effect different degrees of impact , doped before the photocatalytic activity than the undoped material after increased .
