Abstract
A serial of carbon modified Ag/TiO2 photocatalysts have been synthesized with different carbon content by a simple co-impregnation method. Here, 1-pentanol was used as carbon precursor. The carbon modified Ag/TiO2 nanocomposites were characterized by X-ray diffraction, raman spectroscopy, thermal gravity analysis, UV–vis diffuse reflectance spectra, photoluminescence, and X-ray photoelectron spectroscopy. The photocatalytic removal of nitrogen oxides was carried out under both UV light and visible light irradiation. Our results revealed that carbon and silver species showed strong synergistic effect which significantly enhance the photocatalytic NOx removal on TiO2 photocatalyst under visible light irradiation.
