Direct propane dehydrogenation (PDH) to propylene is a desirable commercial reaction but highly endothermic and severely limited by thermodynamic equilibrium. Routes that oxidatively remove hydrogen as water have safety cost challenges. We coupled chemical looping-selective (H2) combustion PDH with multifunctional ferric vanadate-vanadium oxide (FeVO4-VOx) redox catalysts. Well-dispersed VOx supported on aluminum (Al2O3) provides sites, adjacent nanoscale FeVO4 acts an oxygen carrier for...
Redox catalysts play a vital role in chemical looping oxidative dehydrogenation processes, which have recently been considered to be promising prospect for propylene production. This work describes the coupling of surface acid catalysis and selective oxidation from lattice oxygen over MoO3-Fe2O3 redox promoted Atomically dispersed Mo species γ-Fe2O3 introduce effective sites promotion propane conversion. In addition, could also regulate activity, makes reduction Fe3O4 contribute selectively...
Abstract Metal nanostructures with an ultrathin Pt skin and abundant surface defects are attractive for electrocatalytic applications owing to the increased utilization efficiency of atoms presence highly reactive sites. This paper reports a conformal, layer‐by‐layer deposition on defective Rh nanowires faithful replication (i.e., grain boundaries) nanowires. The thickness shell can be controlled from one monolayer up 5.3 atomic layers. series Rh@Pt n L ( = 1–5.3) core–sheath show greatly...
Atomic edge sites on two-dimensional (2D) nanomaterials display striking catalytic behavior, whereas engineering for 2D metal nanocatalysts remains an insurmountable challenge. Here we advance a one-pot synthesis of ultrathin PdPtCu trimetallic nanosheets and nanorings with escalating low-coordinated proportions from 11.74% 23.11% to 45.85% as cutting-edge ethanol oxidation reaction (EOR) electrocatalysts. This in situ enrichment hinges competitive surface capping etching strategy integrated...
Concavity-tunable Rh@Pt core–shell nanocubes with an engineered Rh–Pt interface and Pt atomic steps facilitate C–C bond cleavage in the EOR.
Nanosized crystalline ceria (CeO2) is synthesized through a surfactant- and template-free solution precipitation-hydrothermal method. We report that pure CeO2 nanocrystals with shapes consisting of nanospheres, nanowires, nanorods can be obtained simply by varying the anionic composition or type counter ion, such as chloride, nitrate phosphate in before hydrothermal treatment. The shape-controlling effect these anions explained selective interaction ions specific facets CeO2, leading to...
Monocrystalline Pt–Ni nanocages were successfully fabricated and exhibited great catalytic activity enhanced stability for HER in alkaline solution.
Predictable synthesis of bimetallic nanocrystals with spatially controlled metal distributions offers a versatile route to the development highly efficient nanocatalysts. Here we report one-pot super branched Rh-on-Cu nanoscale sea urchins (Rh–Cu NSUrs) high density Cu–Rh interfaces by manipulating ligand coordination chemistry. Structural analysis and UV–vis spectra reveal that ascorbic acid can serve as Rh-selective in nonaqueous reverse reduction potentials Rh3+ Cu2+ cations. The...
Coating an ultrathin platinum-rich skin on nanosubstrates made of other cheaper metals is effective strategy for fabricating active electrocatalysts with low Pt-content. We developed a facile one-pot synthesis Pd@Pt3Ni core-shell nanobranches Pt3Ni{111} skins that have and durable catalytic performances ethanol electrooxidation.
Ternary PtCoRh spiral nanowires with surface atomic steps and anti-corrosive Rh incorporation can serve as active robust MOR electrocatalysts in acidic media.
In recent times, the fabrication of noble metal-based catalysts with controllable morphologies has become a research hotspot. Electrocatalytic devices excellent catalytic performance and enhanced durability for ethylene glycol oxidation reaction (EGOR) glycerol (GOR) are significant commercial direct fuel cells. Herein, series PdPb sea urchin-like nanodendrite (ND) structures molar ratios were synthesized as EGOR GOR electrocatalysts high efficiency. The optimized structurally regular Pd3Pb...
Abstract Defective metal nanostructures have attracted great attention due to the striking catalytic behavior of defect sites. Atypical nanocrystals generated from attached nuclei can accommodate abundant grain boundaries (GBs) and twin (TBs). However, understanding their growth‐mechanism precisely synthetic control over such defective are still scarce. Herein, using Rh−Pt nanoalloy as a model system, we systematically demonstrate that prudent reaction kinetics manipulate nucleation nucleus...
