摘要：

In this study, we demonstrate that aerosol assisted flow synthesized B. N-codoped TiO2 photocatalyst possesses superior photocatalytic activity to pure and single element doped counterparts on the degradation of NO in a flow system under both simulated solar light and visible light irradiation. Characterization results revealed that B, N-codoped TiO2 photocatalyst was composed of hollow microspheres. Boron and nitrogen were in the form of Ti-O-B and N-Ti-O structures, respectively. The introduction of B and N into the TiO2 lattice could effectively tune the band gap of TiO2 and extend its optical response to the visible-light region. The synergistic effect of B and N codoping on visible light driven photocatalytic activity enhancement of TiO2 was discussed on the basis of experimental results. (C) 2011 Elsevier B.V.
