The Study of Photocatalytic Oxidation of Benzyl Alcohol with g-C_3N_4 under Visible Light: Effect of pH and Salt

摘要

Carbon nitride is a representative metal-free photocatalyst for green chemical technology. In this study, synthesized g-C_3N_4 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 K_2HPO_4 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.
