Abstract

The effect of boron doping on the photocatalytic activity of manganese (Mn) oxide in aniline degradation was investigated. Mn oxide was synthesized by the reaction of MnCl2 with KMnO4 and boron-doped Mn oxide (occluded-B–Mn oxide or oc-B–Mn oxide) was prepared by the reaction of MnCl2 with KMnO4 in the presence of boric acid. The structural formulas of the Mn oxide and the oc-B–Mn oxide were K0.04MnO1.90(H2O)0.54 and K0.04B0.01MnO1.87(H2O)0.61, respectively. Their physicochemical properties were characterized by XRD, TEM, BET and UV–Vis absorption spectra. The photocatalytic activity was evaluated by aniline degradation in aqueous catalyst dispersions under UV light radiation. Discussion of the results showed that the higher photocatalytic activity of the oc-B–Mn oxide may be attributed to the synergetic effect of light absorption, the specific surface area and the suppression of recombination of electron–hole pair.
