In the field of electrochemical energy conversion and synthesis, the gas–liquid–solid three-phase interface is the key site determining reaction efficiency, selectivity, and stability. How to achieve the efficient construction and long-term maintenance of this three-phase interface is one of the major common scientific challenges currently faced in electrochemical engineering. Particularly in systems involving hydrogen peroxide electrosynthesis and gas-phase reactants, interfacial mass transfer issues directly constrain industrialization progress. Zhejiang Epai Technology Co., Ltd. has long focused on the research, development, and equipment commercialization of key technologies for green electrosynthesis of H₂O₂, striving to fundamentally break through technical bottlenecks through electrode structure design and interface engineering.
