摘要: Abstract Photocatalysis assisted oxidation of carbon black was performed using TiO 2 photocatalyst under UV illumination in an atmosphere with NO, O and water vapor at 150 °C. Carbon is oxidized mainly to CO while NO selectively converted N . Enhanced concentrations have a positive effect on the rate. At concentration 3000 ppm 13.3% gas phase rate reaches 2.3 μg /mg TiO2 h, formal electron/photon quantum efficiency 0.019. HR SEM images reveal uniform gradual reduction particle size irrespective distance particles presence H O.
