However, it is paramount that there is a way to recover the catalyst after degradation. Based on this problem, this research seeks to evaluate the photocatalytic properties of TiO2 under porous ceramics support for the degradation of Rhodamine B (RhB). TiO2 was synthesized by sol-gel, dried at 100°C and calcined at 400°C. The morphological, optical and structural proprieties of the particles were characterized. The XRD patterns of samples calcined at 400°C showed only the anatase phase, confirmed by Raman. Not heat-treated xerogel was amorphous. The agglomerates are composed of fine particles, in the nanometric scale of 15nm. The bandgap of the powder is 3.21eV, and the surface area is 60.1m2g−1. To evaluate its photocatalytic activity, the anatase TiO2 was supported in a porous ceramic substrate by a dip-coating process. The heterogeneous photocatalysis showed excellent results, with the degradation of up to 83% of RhB. It was possible obtained with successful an efficient technique for the treatment of wastewater with Anatase nanoparticles supported in the ceramic support obtained from of reuse of the residues. ER -
