Photocatalytic production of hydrogen peroxide harnesses solar energy to convert water and dioxygen into H₂O₂ via sequential light-driven redox reactions. Central to this process are two ...

Electrocatalytic synthesis of hydrogen peroxide harnesses the two-electron oxygen reduction reaction (ORR) to convert molecular oxygen into H₂O₂ directly at the electrode–electrolyte interface. This ...

The question of whether water can form hydrogen peroxide should be answered by thermodynamics (see C&EN, June 13, 2022, page 3). If a reaction is possible (spontaneous), then the change in the Gibbs ...
