چکیده

Radiation treatment in the presence of catalysts such as anatase, P25 and bentonite showed an efficient removal of TCE and PCE compared with gamma-irradiation only. The gamma-ray pretreatment of P25 and bentonite enhanced the decomposition of TCE and PCE, respectively. The change of the catalysts by gamma-ray was characterized by EPR spectra. For anatase and bentonite, the peaks in the spectra increased significantly, but the pattern of the spectra changed in the case of P25. The relationship between the peaks and the pollutant decomposition should be further clarified due to the complexity of the spectra.

Photocatalytic Coating Using Titania-Silica Core/Shell Nanoparticles

The photocatalytic coatings were prepared via incorporating the modified titania nanoparticles into epoxy-based inorganic-organic hybrid coatings. Titania nanoparticles were first synthesized from tetra-n-butyl titanate using sol-gel methods by two different calcination treatments, i.e., in mild condition (80°C) and 500°C. The formed anatase nanoparticles were further modified as Titania-Silica...
