Au-TiO2 composite photocatalysis material was fabricated by the photodeposition method. The SEM and TEM images demonstrate that Au-TiO2 NPs are with inerratic geometry and their diameters are in the range of 10 nm to 20 nm. The UV-vis spectra shows the strong peaks in 200-400 nm and near 550 nm which are attributed to the characteristic absorption peak of TiO2 and the strong surface-plasmon-resonance of Au NPs, respectively. Under visible light irradiation, the phenol degradation dynamics constant on Au-TiO2 was 0.008 min-1 which was 4 times of that on Degussa P25. The effects of Au amount on the photocatalytic capability of Au-TiO2 were also investigated.

Freely assembled palladium nanoparticles (Pd NPs) on titania (TiO2) nano photocatalysts were successfully synthesized through a photodeposition method using natural sunlight. This synthesized heterogeneous photocatalyst (Pd/TiO2) was characterized through field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), BET surface area, UV–vis diffuse reflectance spectra (UV-DRS), Raman and photoluminescence (PL) analyses. The simple and smart synthesis anchored well the deposition with controlled Pd NPs size ranging between 17 and 29 nm onto the surface of TiO2. Thus, it gives the characteristic for Pd NPs to absorb light in the visible region obtained through localized surface plasmon resonance (LSPRs). Apparently, the photocatalytic activity of the prepared photocatalysts was evaluated by degrading the endocrine disrupting compound (EDC) amoxicillin (AMX) excited under an artificial visible light source. In the preliminary run, almost complete degradation (97.5%) was achieved in 5 h with 0.5 wt % Pd loading and the degradation followed pseudo-first-order kinetics. The reusability trend proved the photostability of the prepared photocatalysts. Hence, the study provides a new insight about the modification of TiO2 with noble metals in order to enhance the absorption in the visible-light region for superior photocatalytic performance.
