Removal of As(III) from Water by Cellulase Templated TiO2: A Photocatalytic Oxidation Conjugated Adsorption Process

TiO2 photocatalyst was prepared using cellulase as a biotemplate through hydrothermal process. The as-prepared catalyst characterized based on physicochemical techniques and used to remove As(III) from contaminated water. templated (TiO2-cellulase) had large specific surface area, which reached 166.6 m2·g–1. It also strong oxidation ability and, thus, behaved well in both photocatalytic of dark adsorption. pH the solution negligible effect removal rate. TiO2-cellulase higher rate than commercial Degussa P25 TiO2.
