Description
Summary:•An overview of in situ H2O2 formation in selective oxidation reactions is addressed.•The relationship between catalyst properties and performance is discussed.•The current processes, catalysts in progress and future challenges are reported. One-pot combination of the in-situ generation of hydrogen peroxide (H2O2) with selective oxidation reactions enhances the environmental and economic attractiveness of the use of H2O2 as green oxidant at industrial scale. This tandem reaction improves not only the safety aspects associated to H2O2 storage and transportation but also reduces the capital and operation costs. This review covers the progress in the field focussing on the areas of catalysis development, mechanistic understanding and engineering approaches (such as membrane reactors) for specific systems involving epoxidation of propylene oxide, hydroxylation of benzene, oxygenate synthesis from methane and Fenton processes, highlighting the main challenges to overcome in the near future.
