Abstract

This study focuses on the synthesis of a ternary material via a solvothermal process, followed by a calcination route. Spherical TiO2 nanoparticles were immobilized on raw Algerian diatomite, purified with phosphoric acid. The prepared composites were calcined at 300 °C for 2 hours and then were characterized using various techniques. The results revealed that TiO2/diatomite hybrid catalysis exhibited superior distribution over the support surface. Calcined TiO2 raw diatomite (CTRD) and calcined TiO2 phosphoric diatomite (CTPD), the morphology showed a layer of TiO2 anatase deposited on the CTRD surface. The calculated particle sizes of three materials were in the range of 66-80 nm. The photocatalytic degradation of CTPD enhanced degradation of Metronidazole (MTZ) to 99.30% and resulted in 96.25% of Evans Blue dye (EB) degradation. The three composite significantly increased the photocatalytic activity of TiO2, with diatomite effectively hindering the growth of TiO2 grains on its surface.
