| dc.description.abstractEn | Mineralization of phenazopyridine, <strong>1</strong>, in water, under solar-simulator radiation was efficiently achieved using nanoparticle CdS-sensitized rutile TiO<sub>2</sub>, TiO<sub>2</sub>/CdS, <strong>2</strong>, as photo-catalysts. Despite that, <strong>2</strong> showed two main drawbacks. Firstly, the system was difficult to recover by simple filtration, and demanded centrifugation. Secondly, the sensitizer CdS showed relatively high tendency to leach out hazardous Cd<sup>2+</sup> ions under photo-degradation reaction conditions. In an attempt to solve out such difficulties, <strong>2</strong> was supported onto sand surface. The sand/TiO<sub>2</sub>/CdS system, <strong>3</strong>, was easier to recover but showed slightly lower catalytic activity compared to <strong>2</strong>. On the other hand, the support failed to prevent leaching of Cd<sup>2+</sup>. This indicates limited future applicability of CdS-sensitized TiO<sub>2</sub> photo-catalyst systems, in solar-based water purification strategies, unless leaching out tendency is completely prevented. | |
