Glucose-assisted ball milling preparation of silver-doped biphasic TiO2 for efficient photodegradation of Rhodamine B: Effect of silver-dopant loading

Herein, 0?5 mol% of Silver-doped TiO2 composites were prepared via glucose-assisted ball-milling. The morphology of all composites were observed by scattering electron microscopy. Powder X-ray diffraction confirmed the existence of both anatase and rutile phases with different loading. The diffuse reflectance spectroscopy revealed a slight surface Plasmon resonance peak in the visible region, increasing its broad intensity from 1 to 5 mol%. The band gap energy varies depending on the Ag loading. The photodegradation of Rhodamine B was performed under UV irradiations. Photocatalysis tests shows that RhB?s degradation is higher for TiO2 doped with 3% of Ag.

Automated summary

In this study, Silver-doped TiO2 composites with varying loading levels were prepared using glucose-assisted ball-milling. Characterization techniques including electron microscopy and X-ray diffraction were used to analyze the morphology and phases of the composites. The results showed that the photocatalytic degradation of Rhodamine B was most effective when using TiO2 doped with 3% of Ag, indicating an enhancement in performance with silver doping.
