Hydrogen peroxide(H2O2) is an important reagent which has been widely used in the industrial fields of electronic,pharmaceutical,papermaking,food,wastewater treatment and so on.Direct catalytic synthesis of hydrogen peroxide from hydrogen and oxygen is an ideal atomic economic reaction route;however,its substantial application is confronted with serious technique challenges.Focusing on the development of direct catalytic synthesis process of hydrogen peroxide from hydrogen and oxygen,this article reviewed the researches on active catalytic components including Pd and bimetallic Pd-Au,solid acid carriers and new kinds of reactors including membrane reactors and micro-channel reactors in recent years.In the view of process integration and intensification.It is necessary to explore the integration between the direct synthesis route hydrogen peroxide with other specific chemical process,so as to avoid redundant concentration,transportation and dilution steps and promote the development of safe and green processes to produce hydrogen peroxide.
