Abstract
B-TiO2 was prepared via a sol-gel method, and was characterized using powder X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectrum (XPS), FT-IR, and N2 adsorption (BET). XRD patterns of B-TiO2 well match the diffraction peaks of anatase TiO2 crystallite, accompanied by a restrained crystallite growing with increasing boron content. The samples with fairly rough surfaces are composed of irregular particles in the size range within 2 μm. When boron content increases from 1% to 20%, surface area of the samples increases constantly from 117 to 220 m2/g. Average pore diameter and accumulative pore volume become larger after the addition of boron. The incorporated boron mainly occupies the internal space of TiO2 crystalline structure, existing in the form of B-O-Ti. The sample doped with 3wt% boron shows the optimal photocatalytic activity on degradation of methyl orange. After 90 min of UV-light irradiation, degradation efficiency of methyl orange is 96.7% on 3%B-TiO2 powder, whereas 120 min is needed to achieve fully degradation of the dye on pure TiO2 powder.
