Electrocatalytic water splitting driven by renewable electricity has been recognized as a promising approach for green hydrogen production. Different from conventional strategies in developing electrocatalysts the two half-reactions of (e.g., and oxygen evolution reactions, HER OER) separately, there growing interest designing bifunctional electrocatalysts, which are able to catalyze both OER. In addition, considering high overpotentials required OER while limited value produced oxygen, is another rapidly exploring alternative oxidation reactions replace hybrid toward energy-efficient generation. This Review begins with an introduction on fundamental aspects splitting, followed thorough discussion various physicochemical characterization techniques that frequently employed probing active sites, emphasis reconstruction during redox electrolysis. The design, synthesis, performance diverse based noble metals, nonprecious metal-free nanocarbons, overall acidic alkaline electrolytes, thoroughly summarized compared. Next, their application also presented, wherein anodic include sacrificing agents oxidation, pollutants oxidative degradation, organics upgrading. Finally, concise statement current challenges future opportunities presented hope guiding endeavors quest sustainable

Medium-entropy alloy aerogels (MEAAs) with the advantages of both multimetallic alloys and are promising new materials in catalytic applications. However, limited by immiscible behavior different metals, achieving single-phase MEAAs is still a grand challenge. Herein, general strategy for preparing ultralight 3D porous lowest density 39.3 mg cm-3 among metal reported, through combining auto-combustion subsequent low-temperature reduction procedures. The homogenous mixing precursors at ionic level makes short-range diffusion atoms possible to drive formation MEAAs. As proof concept catalysis, as-synthesized Ni50 Co15 Fe30 Cu5 exhibit high mass activity 1.62 A mg-1 specific 132.24 mA cm-2 toward methanol oxidation reactions, much higher than those low-entropy counterparts. In situ Fourier transform infrared NMR spectroscopies reveal that can enable highly selective conversion formate. Most importantly, methanol-oxidation-assisted MEAAs-based water electrolyzer achieve low cell voltage 1.476 V 10 making value-added formate anode H2 cathode, 173 mV lower traditional alkaline electrolyzers.

Electrocatalysis underpins the renewable electrochemical conversions for sustainability, which further replies on metallic nanocrystals as vital electrocatalysts. Intermetallic have been known to show distinct properties compared their disordered counterparts, and long explored functional improvements. Tremendous progresses made in past few years, with notable trend of more precise engineering down an atomic level investigation transferring into practical membrane electrode assembly (MEA), motivates this timely review. After addressing basic thermodynamic kinetic fundamentals, we discuss classic latest synthetic strategies that enable not only formation intermetallic phase but also rational control other catalysis-determinant structural parameters, such size morphology. We demonstrate emerging nanomaterials potentially advancement energy electrocatalysis. Then, state-of-the-art characterizations representative electrocatalysts emphasis oxygen reduction reaction evaluated a MEA setup. summarize review by laying out existing challenges offering perspective future research directions toward practicing conversions.
