ABSTRACT
As an important advanced oxidation technology for environmental purification, photocatalytic degradation has received extensive attention. Designing and synthesizing a catalyst with high-intensity photocatalytic performance is a very challenging subject. Herein, one polydentate cation was synthesized by 1,4-diazabicyclo[2.2.2]octane (DABCO) and 1, 4-bis (bromomethyl) benzene. Inorganic-organic hybrid compounds 1, 2 were synthesized by hydrothermal and room temperature volatilization with inorganic metal salts, namely, {[L1]0.5·[Cu2Br4]0.5}n (1), {[L1]·[Cu2I4]·CH3CN}n (2). Under visible light, compounds 1 and 2 were investigated for their degradation effects on tetracycline (TC) in water. The experimental results showed that compounds 1 and 2 with appropriate concentration of H2O2 had obvious photocatalytic degradation effect on TC. In addition, the influencing factors of photocatalysis such as the amount of adsorbent, the initial concentration of TC and the different pH value were investigated. The photocatalyst exhibits good stability and cyclability.
