High-entropy alloy nanoparticles (HEA NPs) have aroused great interest globally with their unique electrochemical, catalytic, and mechanical properties, as well diverse activity multielement tunability for multi-step reactions. Herein, a facile low-temperature synthesis method at atmospheric pressure is employed to synthesize Pd-enriched-HEA-core Pt-enriched-HEA-shell NPs single phase of face-centred cubic structure. Interestingly, the lattice both enlarge during formation process HEA, tensile strains included in core shell HEA. The as-obtained PdAgSn/PtBi HEA show excellent electrocatalytic durability methanol oxidation reaction (MOR) ethanol (EOR). specific (mass) MOR 4.7 mA cm-2 (2874 mg(Pd+Pt)-1 ), about 1.7 (5.9) 1.5 (4.8) times higher than that commercial Pd/C Pt/C catalysts, respectively. Additional high-entropy effect, Pt sites Pd on interface act synergistically facilitate towards EOR. This study offers promising way find feasible route scalable manufacturing applications.

Revealing the Charge Storage Mechanism in Porous Carbon to Achieve Efficient K Ion Storage

Small, Год журнала: 2024, Номер 20(32)

Опубликована: Март 25, 2024

Abstract Constructing a porous structure is considered an appealing strategy to improve the electrochemical properties of carbon anodes for potassium‐ion batteries (PIBs). Nevertheless, correlation between K‐storage performance and pore has not been well elucidated, which hinders development high‐performance anodes. Herein, various carbons are synthesized with porosity structures ranging from micropores micro/mesopores mesopores, systematic investigations conducted establish relationship characteristics performance. It found that fail afford accessible active sites K ion storage, whereas mesopores can provide abundant surface adsorption sites, enlarged interlayer spacing facilitates intercalation process, thus resulting in significantly improved performances. Consequently, PCa electrode prominent mesoporous achieves highest reversible capacity 421.7 mAh g −1 excellent rate capability 191.8 at 5 C. Furthermore, assembled hybrid capacitor realizes impressive energy density 151.7 Wh kg power 398 W . The proposed work only deepens understanding potassium storage materials distinctive porosities but also paves path toward developing PIBs customized capabilities.

Опубликована: Июль 3, 2023

Environmental worsening, energy crises, and various other factors have enhanced the demand for facile, cheap, green approaches creating emerging materials from bioresources. In recent times, graphene quantum dots (GQDs) are most developing zero-dimensional nanomaterials owing to exclusive electronic optical properties. Biomass-derived GQDs been considered an advanced material gained complete attention because of their green, inexpensive, nonsustainable, environmental-friendly, recyclable nature. This review elucidates current challenges use bioprecursors (e.g., rice husk, plant leaves, honey, coffee) methodologies (top-down bottom-up) conversion into ecofriendly GQDs. Biomass resources converted a low-cost, scalable synthesis. in great due attractive properties like large surface area, low toxicity, good biocompatibility. Various parameters absorption, edge states, confinement affecting physical, chemical, electrochemical discussed. also focuses further on result heteroatom doping, pH, solvent photoluminescence (PL) emission The sensors based biomass-derived explored detail. tremendous performance biomedical field applications very toxicity addresses future possible research directions display minimal cytotoxic reactivity, superior biocompatibility, chemical insensitivity. To enhance optoelectronic physicochemical characteristics GQDs, can be tuned via surface/edge functionalization or doping. Monitoring concentrations pollution gases severely harming biosphere requires more precise sensitive sensors. Doped significantly increase capacity adsorb. reliable gas doped could viable replacement present available market.
