Preparation and Photocatalytic Properties of Nano Ni/TiO2 Composite in Alginate
New nano nickel-doped titanium dioxide composites had been produced by a conducting sol-gel method.The alginate gel was used as a template to prevent the conglomeration of the inorganic materials.In this experiment,nickel nitrate,tetrabutyl titanate and sodium alginate were used as main materials to prepare different amount nickel-doped TiO2 particles.The amount of Ni was studied from 0 to 9 mol.-% (where mol.-% refers to the Ni/TiO2 molar ratio),and the Ni/TiO2 composites were characterized by XRD,FT-IR,TG-DTA,and we carried out doping amount,catalyst amount and illumination time influence on photocatalytic performance of nano Ni/TiO2 composite in aqueous methyl orange.The activity of TiO2 gradually increased with the increasing of doping amount,and there was highest catalytic efficiency when Ni =9 % mol.
