Figure 4

Optical absorption and photocatalytic property of the as-prepared samples.

(a) UV–visible diffuse reflectance spectra of the as-prepared samples. The insets show photos of the sample color. (b) Photocatalytic activities of (BiO)2CO3, BOC-400, BOC-450 and Bi2O3 and the mechanical mixture composed of 54.99% (BiO)2CO3 and 45.01% Bi2O3 under solar light irradiation for NO removal. (c) Recycling property of the composite photocatalyst BOC-400 under solar light irradiation.
