Abstract
A one-step solvothermal method was used to prepare TiO2/halloysite composites. TiO2 nanoparticles were deposited on the platform of the halloysite nanotubes (HNTs). XRD, FT-IR, FE-SEM, and TEM were applied to investigate the structures and morphologies of the resultant samples. The as-prepared TiO2/HNTs photocatalyst exhibits pH sensibility on the degradation of methanol and a higher photocatalytic activity on the degradation of acetic acid. The combination of the photocatalytic property of TiO2 and the unique structure of halloysite endowed this material with a bright perspective in degradation of organic pollutant.Keywords
