主 题:Solvent-assisted Graphitic carbon nitride Visible light Photocatalytic performance Nitrogen oxide removal
摘 要:Graphitic carbon nitride(g-C3N4) with efficient photocatalytic activity was synthesized through thermal polymerization of thiourea with the addition of water(CN-W) or ethanol(CN-E) at 550 ℃for 2 *** physicochemical properties of the g-C3N4 were investigated by X-ray diffraction,transmission electron microscopy,ultraviolet-visible spectroscopy,photoluminescence spectroscopy,diffuse-reflection spectroscopy,BET and BJH surface area characterization,and elemental *** carbon content was found to have self-doped into the g-C3N4 matrix during the thermal polymerization of thiourea and ***-W and CN-E showed considerably enhanced visible-light photocatalytic activity,with NO removal percentages of 37.2%and 48.3%,*** with pure g-C3N4,both the short and long lifetimes of the charge carriers in CN-W and CN-E were found to be *** mechanism of improved visible-light photocatalytic activity was *** present work may provide a facile route to optimize the microstructure of g-C3N4photocatalysts for high-performance environmental and energy applications.
