Abstract
The present article embraces the photocatalytic previous termoxidationnext term (PCO) of three previous termselected cyclohexyl alcoholsnext term namely cyclohexylmethanol (1), 2-cyclohexylethanol (2) and 1-cyclohexylethanol (3) using previous termnanoparticlesnext term titanium dioxide (TiO2-P25) as a semiconductor photocatalyst in acetonitrile under aerated conditions. The photocatalytic experiments showed moderate conversion ratios (55.2%, 51.8% and 60.3%, respectively). The primary photocatalytic previous termoxidationnext term products are the corresponding aldehydes or ketones and acids. The photocatalytic previous termoxidationnext term products were identified mainly by GC and GC/MS techniques using authentic samples. Formation of electron–hole pair at the surface of the semiconductor previous termnanoparticlesnext term followed by previous termoxidationnext term reaction was the suggested mechanism. A first-order kinetic model was observed for the photocatalytic previous termoxidationnext term of the investigated previous termalcoholsnext term and the rate constants were calculated.
