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 NO_x removal on TiO₂ photocatalyst under visible light irradiation.

通过简单的共浸渍法合成了一系列碳含量不同的碳改性Ag / TiO ₂光催化剂。在此，将1-戊醇用作碳前体。碳改性的Ag / TiO ₂纳米复合材料的特征在于X射线衍射，拉曼光谱，热重分析，紫外可见漫反射光谱，光致发光和X射线光电子能谱。在紫外光和可见光照射下进行光催化氮氧化物的去除。我们的结果表明，碳和银物种显示出强大的协同作用，从而显着增强了可见光照射下TiO ₂光催化剂对光催化NO _x的去除。
