چکیده
In this study, the halloysite nanotube material will be fabricated from a natural mineral and used as support for photocatalytic activity phase based on TiO2. The is characterized by modern physicochemical methods such XRD, SEM, BET, UV - vis spectrum, EDX. Accordingly, refined has nanoscale with length of about 1.3 μm capillary size 5 nm. After deposition Ag TiO2 halloysite, specific surface measured BET method was 60 m2/g, structure intact. band gap energy prepared materials also significantly improved in comparison to pure TiO2, makes capable absorbing longer wavelengths light process. Photocatalyst Halloysite showed very high efficiency, up more than 95% decomposition typical organic pollutant RR 195. This result shows great potential novel environmental treatment applications.

In this work, ZnO/SiO2 nanoparticles were prepared using sol-gel method, and platinum particles were loaded on ZnO/SiO2 nanoparticles by photoreductive method. Samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The XRD patterns showed that the zinc oxide samples have a wurtzite structure (hexagonal phase...
