A Kinetic Study of Photocatalytic Degradation of Phenol over Titania–Silica Mixed Oxide Materials under UV Illumination

A set of titania–silica mixed oxide materials were prepared by a cosolvent-induced gelation method using ethanol and toluene as solvent cosolvent, respectively. These extensively characterized utilizing several characterization techniques assessed for phenol degradation under UV illumination. The follows first-order kinetics, fragmented products formed during the qualitatively identified high performance liquid Chromatographic (HPLC) atomic pressure chemical ionization mass spectroscopic (APCI-MS) techniques. complete mineralization was further evidenced measurement total organic contents that remained in solution after irradiation. pore diameter found to be key factor degradation, whereas surface area volume play role among materials. In addition, system there an inverse correlation obtained with particle size efficiency. smaller titania material requirement effective phenol.
