Green Synthesis of Hydrogen Peroxide from alternative sources Using innovative Photocatalysts.

Hydrogen peroxide (H2O2) is a versatile, environmentally friendly oxidizing agent and considered as one of the 100 most important chemicals in the world. Among the many chemical oxidants available to the chemists, H2O2 is considered as one of the ''greenest'' since the by-product of its oxidation is only water. Additionally, it is also one of the most efficient oxidizing agents by virtue of its high active oxygen content (about 47%), only next to molecular oxygen. The current global market size for hydrogen peroxide (H2O2) has reached to 4 billion USD with a compound annual growth rate of more than 5% from 2020 to 2024. Currently, H2O2 is produced via the anthraquinone oxidation (AO) process and has been successfully used to produce most of the world's H2O2. However, the AO process suffers from several drawbacks, such as use of complex and toxic solvent system, periodic replacement of costly quinone-derivative due to nonselective hydrogenation, deactivation of hydrogenation catalyst, requirements of energy intensive process steps for the removal of organic impurities, etc. Based on these, we have developed an operationally simple and green approach for the synthesis of H2O2 directly from renewable resources using photocatalysis.
