Abstract:
A novel phosphorus doped g-C₃N₄ with typical optical property has been synthesized using phosphonitrilic chloride trimer and thiourea as precursors through a thermal copolymerization route. The samples were characterized by XRD, XPS, TEM, BET-BJH, UV-vis, DRS and PL. Their photocatalytic activities were evaluated by the removal of NO at the indoor air level under visible light irradiation. The typical optical performance and enhanced photocatalytic activity have been investigated in detail. The present work could provide new insight into the appropriate selection of the precursor for photocatalytic materials.
