Preparation and Characterization of TiO2/Coconut-Activated Carbon Photocatalytic Materials
Using Ti (OC4H9)4 as the precursor,and GAC as carrier, making use of technology of hydrolyzation and natural assembling,TiO2/GAC composite material was preparated at the lower temperature.The characterization of obtained TiO2 /Coconut-Activated Carbon’scrystal structure and appearance by XRD and SEM.The adsorption capacity and photocatalytic performance on phenol were measured.Results show that TiO2/GAC surface was well-distributed and remains a little interspace.A nanocrystal TiO2 aerogel size is without 30nm.The sample shows lower adsorption compared to GAC.But photocatalytic efficiency was higher than GAC under the exposure of the sunlight or the violet.
