Microwave-assisted hydrothermal synthesis of monoclinic nitrogen-doped titania photocatalyst and its DeNO(x) ability under visible LED light irradiation

Nitrogen-doped titania (TiO2-xNy) nanoparticles with monoclinic phase were successfully prepared by a microwave-assisted hydrothermal process. The obtained TiO2-xNy powders showed high specific surface area, fine particle size, and excellent photocatalytic ability for the oxidative destruction of nitrogen monoxide under irradiation of monochromatic LED light with various wavelengths.
