Advances in Selective Oxidation of Organic Sulfides by Hydrogen Peroxide over Titanium Catalyst

Hydrogen peroxide (H2O2) is a versatile oxidant used in various chemical syntheses, including the selective oxidation of organic compounds and the conversion of organic pollutants in wastewater. The increasing interest in H2O2 as a “green oxidant” is largely due to environmental considerations assigned to the clean nature of hydrogen peroxide as an oxidant because its by-product is only water. The selected catalytic processes of organic sulfide oxidation, as a method used for the production of valuable chemicals, as well as the potential method of crude oil desulfurization are presented and discussed. Special attention is paid to the various Ti-based catalytic systems used in these processes.
