Abstract Ruthenium dioxide is presently the most active catalyst for oxygen evolution reaction (OER) in acidic media but suffers from severe Ru dissolution resulting high covalency of Ru-O bonds triggering lattice oxidation. Here, we report an interstitial silicon-doping strategy to stabilize highly sites RuO 2 while suppressing The representative Si-RuO −0.1 exhibits activity and stability acid with a negligible degradation rate ~52 μV h −1 800 test overpotential 226 mV at 10 mA cm −2 ....
The serious problem of carbon monoxide (CO) poisoning on the surface Pt-based catalysts has long constrained commercialization proton exchange membrane fuel cells (PEMFCs). Regeneration Pt sites by maintaining CO scavenging ability through precise construction and interface structure catalyst is key to obtaining high-performance CO-resistant catalysts. Here, we used molybdenum carbide (MoC
The rational manipulation of reaction intermediates is crucial for achieving high-performance heterogeneous catalysis. Herein, using in situ Fourier transform infrared-diffuse reflection (FTIR) analysis, we report that the methanol oxidation (MOR) can be controlled by precisely tuning location and content Ru on Pt-Ru alloy surface.
A thermally driven interfacial diffusion strategy was employed to fabricate a trimetallic Pt<sub>3</sub>CoRu/C@NC catalyst with excellent enhancement towards the MOR in terms of superior stability and anti-CO poisoning.
Abstract A new series of rare‐earth‐cerate high‐entropy ceramics with compositions (La 0.2 Nd Sm Gd Dy ) 2 Ce O 7 (HEC1), Yb (HEC2), (HEC3), (HEC4), (HEC5) as well a single component are fabricated via sintering the corresponding sol–gel‐derived powders at 1600°C for 10 h. HEC1–5 samples exhibit single‐cerate phase fluorite structure and high configurational entropy. Compared , have lower grain growth rate owing to sluggish diffusion effect. The chemical compositional uniformity does not...
Abstract Controlled selective growth of an interface with high-density active sites is the key to constructing efficient and long-term stable proton exchange membrane water electrolysis, which can effectively promote acid oxygen evolution reaction (OER). Herein, a two-dimensional all-carbon graphdiyne (GDY) used as ideal support grow new generated RuOx-GDY, finally achieve directed controlled production Ru atom defects. The metal defect-rich not only afforded high intrinsic activity by...
The electronic modulation of Pt to weaken CO adsorption was achieved by triggering strong metal–support interactions on WO x -supported Pt.
The Ni5Zr alloy prepared from the mixture of nickel oxide (NiO) and zirconium (ZrO2) powders by direct electrochemical reduction was conducted in molten lithium chloride (LiCl) at 923 K. behaviors ZrO2 NiO-ZrO2 were firstly investigated cyclic voltammetry measurements. influence process parameters such as composition, compression force, sintering time, cell voltage on electrolysis have been comprehensively evaluated terms reducibility ZrO2. results demonstrated that starts with NiO to Ni...
Abstract A series of (Ba 0.2 Sr Na Ca La )(Zr x Ti 1‐ )O 3 (BSNCLZ T ) ( = 0, 0.05, 0.1, 0.15, and 0.2) high‐entropy ceramics were prepared in forms bulks thin films by conventional sintering spin‐coating, respectively. All ceramic are composed a single perovskite‐structured solid solution. The introduction the Zr element reduces dielectric loss improves frequency stability constant. have higher constant lower than their corresponding films. As rises from 0 to 0.2, breakdown strength E b...
