摘要: The acid–base properties and photocatalytic activity for the degradation of Congo Red methylene blue TiO2-based nanomaterials (commercial TiO2, sulfonated TiO2 (TiO2-S) nanocomposites TiO2-S with carbon nanotubes) have been studied. results indicated important role catalysts influencing on efficacy processes. A correlation between strength acid sites has observed photodegradation blue. Sulphur-free samples (TiO2 P25 TiO2-MWCNT), which are superior in then sulphur-containing catalysts, shown higher (99–100%) photodegradation. Sulphur-containing (TiO2-S TiO2-S-MWCNT) a bifunctional nature were most effective photocatalysts process. This was due to presence both base functional groups dye. obtained suggested crucial adsorption surface as an stage organic dyes
