Abstract

Photocatalytic reduction of p-nitrochlorobenzene was studied over aluminosilicate-based AgBr and AgBr-TiO2 photocatalysts which were prepared and characterized. The photoreaction was performed in the presence of LiBH4, which is a strong reducing agent, in the solution medium. A new mechanism is proposed for reduction of p-nitrochlorobenzene under photocatalytic conditions. The effect of pH, illumination source, LiBH4 concentration, temperature, catalyst dosage, and alcoholic scavengers was also studied. The results showed that the best efficiency was obtained over Ag/AgBr/TiO2/aluminosilicates at natural pH under UV light. We observed that the reaction yield was affected by changing the LiBH4 concentration and temperature, while the effect of former case was more considerable. In addition, it was found that methanol as a hole scavenger has the strongest effect on increasing the photoreduction efficiency. Also, the results for inactivation of Bacillus bacterium indicated that AgBr-modified photocatalysts had the best antibacterial activity, whereas the pure aluminosilicates and TiO2/aluminosilicates did not show any antibacterial activity under visible light and dark conditions.
