Synthesis of activated coconut shell carbon based ternary composite and investigation on its photocatalytic performance for soluble pollutants
Considering the pollution of soluble pollutants on water quality,this study used a simple one-step hydrothermal synthesis process to prepare a ternary composite photocatalytic material(ZnO-TiO2/ACSC)loaded with ZnO and TiO2 on coconut shell activated carbon(ACSC),which was used for photocatalytic degradation of representative soluble organic pollutants under mild conditions.The morphology,structure and other characteristics of the prepared samples were characterized,and their ability to remove rhodamine B and tetracycline from water under 300 W xenon lamp irradiation was investigated to evaluate the photocatalytic performance of the composite material.The results showed that the synergistic adsorption photocatalytic effect of ZnO-TiO2/ACSC on pollutants exhibited higher photocatalytic degradation activity than pure TiO2.After 120 minutes of illumination,the highest degradation rate of rhodamine B on ZnO-TiO2/ACSC reached 89.0％.Similarly,after 120 minutes of illumination,the degradation efficiency of tetracycline reached 82.0％.
