Carbon nitride is a representative metal-free photocatalyst for green chemical technology. In this study, synthesized g-C3N4 carbon nitride was employed to study effect of pH and potassium salt loading on photocatalytic oxidation of benzyl alcohol. The result indicated that the maximum conversion could be achieved to 20.75% at a pH of 8.66 with a concentration of K2HPO4 of 0.6 mmol Suitable pH and salt concentration were important factor for promoting of proton on surface and electronic conductivity to separate electron in photocatalysis.

Titanium dioxide was surface-modified by grafting vanadyl species using vanadyl triisopropoxide as a precursor. The resulting material, (VOx)n/TiO2, was characterized by Raman spectroscopy and photoelectrochemical methods. Photocatalytic oxidation of benzyl alcohol and cyclohexene were used to test oxidation selectivity and 4-nitro-benzaldehyde to assess selective photoreduction. The surface-modified TiO2exhibits an enhanced selectivity to benzaldehyde in the photocatalytic oxidation of benzyl alcohol in an aqueous medium and an increase of cyclohexenol formation in the case of cyclohexene in nonaqueous solvent. The salient result is the 100% selective reduction of the nitrogroup in 4-nitro-benzaldehyde achieved under mild experimental conditions.
