The supported RuO2 catalysts are known for their synergistic and interfacial effects, which significantly enhance both catalytic activity stability. However, polymer-supported have received limited attention due to challenges associated with poor conductivity. In this study, we successfully synthesized the RuO2-polytetrafluoroethylene (PTFE) catalyst via a facile annealing process. optimized nucleation growth strategies enable formation of particles (~13.4 nm) encapsulating PTFE, establishing conductive network that effectively addresses conductivity issue. Additionally, PTFE induces generation oxygen vacancies stable RuO2/PTFE interfaces, further acidic OER stability RuO2. As result, RuO2-PTFE exhibits low overpotential 219 mV at 10 mA cm⁻2 in three-electrode system, voltage RuO2-PTFE||commercial Pt/C system can keep 1.50 V 800 h cm−2. This work underscores versatility as substrate fine-tuning morphology, crystal defect, interface outerwear. not only broadens application scope synthesis but also provides novel approach design high-performance metallic oxide tailored vacancy concentration polymer

Abstract Electrocatalytic water splitting has emerged as a key method for large‐scale production of green hydrogen. Constructing efficient, durable, and low‐cost electrocatalysts the hydrogen evolution reaction at high current densities is prerequisite practical industrial applications splitting. Recently, non‐noble metal‐based self‐supporting electrodes have been explored density due to their cost‐effective, conductivity metal substrate, robust interfacial binding between catalyst strong mechanical stability. In this review, recently reported (Ni, Fe, Cu, Co, Ti, Mo, alloy) electrode applied are comprehensively summarized, classified, discussed. Five fundamental design principles such intrinsic activity, abundant active sites, fast electron transfer, mass transport, stability proposed discussed achieve high‐performance under densities. Furthermore, various modification strategies including heteroatom doping, morphology engineering, interface phase strain engineering enhance catalytic activity durability electrode. Finally, challenges prospects designing efficient stable in future This comprehensive overview will provide valuable insight guidance development production.

Regulating the surface oxophilicity of electrocatalyst is known as an efficient strategy to mitigate order-of-magnitude kinetic slowdown hydrogen electrocatalysis in a base, which great scientific and technological significance. So far, its mechanistic origin remains mainly ascribed bifunctional or electronic effects that revolve around catalyst-intermediate interactions under extensive debate. In addition, understanding from perspective interfacial electric-double-layer (EDL) structures, should also strongly depend on electrode property, still lacking. Here, by decorating Pt with Mo, Ru, Rh, Au metal atoms tune systematically combining electrochemical activity tests, situ surface-enhanced infrared absorption spectroscopy, density functional theory calculation, ab initio molecular dynamics simulation, we found there exist consistent volcano-type relationships between *OH adsorption strength alkaline evolution activity, stretching/bending vibration information water, potential zero charge (PZC) electrode. This demonstrates impacting electrocatalytic lies modification toward PZC, thereby dictates electric field strength, rigidity, bonding network structure EDL ultimately governs proton transfer kinetics. These findings emphasize importance focusing interface structures understand property-dependent reaction

Constructing electrocatalysts with high activity and low precious metal content is essential for achieving efficient hydrogen production in pH-universal overall water splitting. Herein, five types of noble anchored transition phosphides are analyzed by theoretical derivation. Based on the calculation results, a suitable hybrid screened out Pt nanoparticles CoP nanowires (Pt─CoP) via robust Pt─P─Co bonds. This strong synergy between through interfacial bonds optimizes adsorption key intermediates evolution reaction (HER) wide pH range from 0 to 14. Furthermore, interaction accompanied delicate structure reduces charge transfer resistance, creates abundant active sites, enhances catalyst durability, while facilitating site exposure electron/mass during HER process. Accordingly, synthesized Pt─CoP exhibits overpotentials 79, 26, 18 mV at 10 mA cm-2 acidic, neutral, alkaline media HER, respectively, superior commercial Pt/C benchmarks most reported electrocatalysts. work paves new clue exploit low-Pt-loading HER.
