Comparison of different advanced oxidation processes for phenol degradation.

Advanced oxidation processes (AOPs) involving ultrasound for waste water treatment: A review with emphasis on cost estimation

Noble metal nanoparticles (Au, Pd, Au–Pd alloys) with a narrow size distribution supported on nanocrystalline TiO2 (M/TiO2) have been synthesized via a sol-immobilization route. The effect of metal identity and size on the photocatalytic performance of M/TiO2 has been systematically investigated using phenol as a probe molecule. A different phenol degradation pathway was observed when using M/TiO2 catalysts as compared to pristine TiO2. We propose a mechanism to illustrate how the noble metal nanoparticles enhance the efficiency of phenol decomposition based on photoreduction of p-benzoquinone under anaerobic conditions. Our results suggest that the metal nanoparticles not only play a role in capturing photogenerated electrons, but are strongly involved in the photocatalytic reaction mechanism. The analysis of the reaction intermediates allows us to conclude that on M/TiO2 undesired redox reactions that consume photogenerated radicals are effectively suppressed. The analysis of the final products shows th...
