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 production. Therefore, this paper reviews a series construction strategies, including solvothermal method, gas-phase chemical heat treatment reduction electromagnetic electrochemical constructing heterojunctions method and substrates method. These methods significantly enhance overall performance by optimizing interactions between catalyst support materials, improving electron transfer efficiency, increasing exposed area active sites. Additionally, introduces various that can increase HER sites, such as single-atom catalysts, diatomic nanoparticles, nanowires, nanotubes, porous structures. nanostructures further catalytic activity stability specific surface providing abundant Furthermore, thoroughly elucidates mechanisms acidic alkaline media, exploring key factors under different pH conditions. By understanding combining advanced with diverse nanostructure designs, researchers better construct interfaces design nanostructures, thereby developing efficient, stable, economical. This review provides systematic guide structures platinum compounds, aiming to promote sustainable development technologies, facilitate widespread transition, contribute achieving carbon neutrality goals addressing severe environmental challenges.

Abstract The controlled regulation of A‐site in rare earth manganate perovskites can orderly arrange the electronic states, leading to emergence unique transport properties. However, it is challenging balance crystal structure stability and property variations during multi‐ion doping. In this study, a series multivalent are synthesized by hydrothermal method through multielement doping, which enables manganese atoms with varying valence states at B site. Powder X‐ray diffraction (PXRD) absorption spectra (XAS) confirm that splitting K─O hybrid orbitals effectively prevents any distortion MnO 6 octahedron, thereby facilitating ordered arrangement Mn (III) ‐Mn (IV) (V) B‐site promoting superstructure formation. transient (TAS) reveals sequential – Mn(V) better forms charge transfer channels, makes photodynamic properties sample composition‐dependent.

Abstract Hydrogen, known for its high energy density and environmental benefits, serves as a prime substitute fossil fuels. Nonetheless, the hydrogen evolution reaction (HER), essential in electrolysis, encounters challenges with slow kinetics significant overpotential, which elevate costs reduce efficiency. Thus, developing efficient electrocatalysts to HER overpotential is vital enhance production efficiency minimize consumption. Adjusting electronic structure of transition metal oxides via elemental doping potent strategy improve effectiveness evolution. In this work, we synthesized set niobium‐doped tungsten (Nb x ‐W 18 O 49 ) under anoxic conditions using straightforward “one‐pot” solvothermal approach. After Nb, oxygen vacancy content inside W was increased, induced synergistic effect active sites tungsten. acidic environments, activity Nb 0.6 electrocatalyst second only by 20 wt % Pt/C.
