AbstractThe photocatalytic degradation of a variety of carbohydrates in solution, including mono-, di-, and poly-saccharides, has been investigated under unaerated conditions with the use of a Pt/TiO2 catalyst and a solar light simulating source. It has been found that, even in the absence of oxygen, complete oxidation of carbohydrates toward CO

A series of advanced WO3-based photocatalysts including CuO/WO3, Pd/WO3, and Pt/WO3were synthesized for the photocatalytic removal of microcystin-LR (MC-LR) under simulated solar light. In the present study, Pt/WO3exhibited the best performance for the photocatalytic degradation of MC-LR. The MC-LR degradation can be described by pseudo-first-order kinetic model. Chloride ion (Cl−) with proper concentration could enhance the MC-LR degradation. The presence of metal cations (Cu2+and Fe3+) improved the photocatalytic degradation of MC-LR. This study suggests that Pt/WO3photocatalytic oxidation under solar light is a promising option for the purification of water containing MC-LR.

Flower like bismuth oxy chloride (BiOCl) was successfully synthesized by a simple hydrolytic method at room temperature. The precursor and as-prepared samples were characterized by X-ray diffraction (XRD), High Resolution Field Emission Scanning Electron Microscope (HR FESEM). The results indicated that the as-prepared BiOCl sample is self-assembled hierarchically with nano sheets. The photocatalytic activity of BiOCl was tested on the degradation of the Oxamyl (OM) under solar light irradiation. The results showed that pesticide molecules could be efficiently degraded over BiOCl under solar light irradiation. All the experiment were carried out in the following reaction condition, [OM] = 10-4 mol dm-3, BiOCl NPs= 40mg/50ml, pH= 6.3. Effect of operational parameter such as concentration of H2O2, K2S2O8, FeCl3, Fenton’s reagent (Fe3+/H2O2) and N2, O2 purging on the photocatalytic degradation was observed.
