Hydrogen peroxide (H2O2) synthesis generally involves high temperature and pressure, huge energy consumption, and toxic byproduct emission. Exploring green, safe, sustainable, and energy-saving protocols for stable H2O2 evolution is meaningful and urgent. This Perspective systematically outlines the mainstream methods (electrocatalytic two-electron oxygen reduction, photocatalytic reaction, novel zero-energy consumption synthesis, etc.) for catalytic H2O2 synthesis at room temperature and pressure. It also summarizes the key factors in catalyst design, reaction mechanisms, and interface regulation, analyzes the current technique bottlenecks, such as selectivity, yield, stability, and concentration accumulation, and proposes future development directions for industrial H2O2 production. This paper is expected to spur certain innovative ideas for optimizing the current H2O2 synthesis systems.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the surface of...
