| مستخلص: | Recent years have seen increased research on green H2O2production by photocatalysis. Though the H2O2formation by photocatalysis is still at a dilute level, it is sufficient to degrade a given organic pollutant by a photo-Fenton process. The in situFenton process avoids the costs of H2O2storage and transportation and uses it more efficiently. The present review is on the in situFenton use of the H2O2formed by photocatalysis. Though this technique is called the in situFenton process, converting H2O2to hydroxyl radicals (·OH) has, to date, always been achieved under light irradiation or photo-Fenton conditions. We do a thorough literature survey of the present status of such in situFenton reactions and classify them into three types based on the photocatalyst and the reaction system composition. The H2O2-producing photocatalyst is also the main player in the in situFenton generation of ·OH. Mechanism inputs are drawn from the latest photo-Fenton research to understand the in situFenton process better. The review ends by listing the future challenges and perspectives in this nascent area of research. |
