Abstract：Aiming attheproblem of poorphotocatalytic eficiencyof traditional photocatalyst materials，a compositephotocatalyst wasproposed，and thephotocatalytic eficiencyand photocatalyticactive specieswereanalyzed. Theresults showed thatthe photocatalytic degradationof tetracycline bythecomposite photocatalystreached equilibriumat6O min，andthe catalytic C（rVI）reached equilibrium at9O min.The photocatalytic degradation fficiency of the two pollutants exceeded 90% ，showing good photocatalytic degradation effect. After 8 times of repeated catalysis，thedegradationeficiencyof tetracyclinebythecomposite photocatalystremained stable，showing goodreusability and stability.The photocatalytic active species were analyzed，and the active substances of the photocatalyst in the photocatalytic degradation process were determined to be ·OH， ⋅O2- ，and h+ ，respectively.
