Title: Preparation of uniform rhodamine B-doped SiO{sub 2}/TiO{sub 2} composite microspheres

Abstract

Uniform rhodamine B (RB)-doped SiO{sub 2}/TiO{sub 2} composite microspheres with catalytic and fluorescent properties were prepared by an easy and economical method in this paper. The composite microspheres were built up with well-dispersed silica particles as the cores, RB as both the doped agent and stabilizer, and the TiO{sub 2} shells were obtained through the hydrolysis of TiCl{sub 4} in water bath. The morphology and structure of the particles were characterized by scanning electron microscopy (SEM) and X-ray powder diffraction (XRD). The characterization results indicate that composite particles are all in spherical shape and have a narrow size distribution. The composite particles calcined above 500 deg. C reveal clear crystalline reflection peaks of the rutile TiO{sub 2} which exhibits well catalytic property. The photocatalytic experiment was carried out in order to examine the catalytic property of composite microspheres. The fluorescent property of particles was also investigated. Dye-leakage test indicates that RB molecules entrapped in the composite particles by this method are stable inside the particles.
