Platinum Compounds Constructing Interface Structures Strategies for Electrolysis Hydrogen Production

With the continuous growth of global energy demand, designing efficient hydrogen evolution reaction (HER) catalysts has become increasingly important. However, current interface structure synthesis strategies for platinum-based compounds are not yet adequate, limiting their application efficiency in hydrogen production. Therefore, this paper reviews a series of interface construction strategies, including the solvothermal method, gas-phase chemical method, heat treatment method, reduction method, electromagnetic synthesis method, electrochemical method, constructing heterojunctions method and constructing substrates method. These methods significantly enhance the overall performance of platinum-based catalysts by optimizing the interactions between the catalyst and support materials, improving electron transfer efficiency, and increasing the exposed area of active sites. Additionally, this paper introduces various interface structure strategies that can increase HER active sites, such as single-atom catalysts, diatomic catalysts, nanoparticles, nanowires, nanotubes, and porous structures. These nanostructures further enhance catalytic activity and stability by increasing the specific surface area and providing abundant reaction sites. Furthermore, this paper thoroughly elucidates the mechanisms of the HER in acidic and alkaline media, exploring the key factors for optimizing catalyst performance under different pH conditions. By understanding the HER mechanisms and combining advanced interface construction strategies with diverse nanostructure designs, researchers can better construct interfaces and design nanostructures, thereby developing platinum-based catalysts that are efficient, stable, and economical. This review provides a systematic guide for constructing interface structures of platinum compounds, aiming to promote the sustainable development of hydrogen energy technologies, facilitate their widespread application in the global energy transition, and contribute to achieving carbon neutrality goals and addressing increasingly severe environmental challenges.
