The development of efficient electrocatalysts for the complete oxidation ethylene glycol (EG) is crucial enhancing practicality direct EG fuel cells (DEGFCs). However, significant challenges persist in developing highly active Pd-based catalytic electrodes. In this work, PdIrNi ternary telluride nanospheres (PdIrNiTe-MNSPs) with mesoporous morphology and an amorphous structure were successfully synthesized applied electrocatalytic reaction. Brunauer–Emmett–Teller analysis revealed typical characteristics, a surface area 8.33 m2·g−1 total pore volume 0.055 cm3·g−1, respectively. Transmission electron microscopy characterization showed that outer layer PdIrNiTe-MNSPs entirely structure. Electrochemical tests demonstrated exhibit enhanced specific activity (16.75 mA·cm−2) mass (1372.22 mA·mg−1) reaction (EGOR), achieving 3.17 2.09 times higher than commercial Pd/C, which can be attributed to its unique nanoarchitecture optimized configuration. situ spectroscopy incorporation IrNi, facilitate C-C bond cleavage EG, selectivity (≈93%) oxidizing C1 products, while PdTe-MNSPs glycolic acid EGOR. Taken together, work provides new insights into application nanomaterials electrocatalysis

Metal sulfide materials, endowed with ordered mesoporosity, offer ample opportunities in a variety of renewable energy applications due to the integration intrinsic functional properties and enhanced reaction kinetics. Unfortunately, mesoporous metal sulfides have rarely been reported immense synthetic difficulties by conventional self-assembly approaches. Herein, we explore compatible coordinated ionic strategy for facile synthesis highly Pt2Sn2S6 networks templated mesopores at 4.2 nm hexagonal mesophase (space group p6mm) accessible surface area. The mechanism is further investigated, revealing role cationic surfactant anionic sulfur pair balancing suitable interaction utilized ammonia ligand retard fast precipitation source effective assembly. Owing combination porosity functionality, after crystallization exhibits excellent activity (overpotential 13 mV, Tafel slope 34 mV dec-1) long-term durability over 100 h electrochemical hydrogen evolution (HER) alkaline solution. Our study provides toolbox rational compositions as advanced model platforms future versatile technologies.

Oxygen‐Bridged Ga‐O‐PtPd Triple Sites Boost Methanol‐Assisted Rechargeable Zn‐Air Batteries Through Suppressing CO_ads Generation

Advanced Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 4, 2025

Abstract Constructing high‐efficiency platinum (Pt)‐based catalysts for methanol oxidation reaction (MOR) by suppressing the intermediate CO ads generation is strongly desired and remains a grand challenge. Herein, concept of holding O‐bridged triple sites documented to strengthen “non‐CO” pathway selectivity forming HCOO − species during MOR. The obtained Ga‐O‐PtPd via grafting single‐atomic Ga on PtPd nanosheets achieves high current density 3.05 mAcm −2 MOR, which 5.65 times higher than commercial Pt/C (0.54 ), as well remarkably stability poison resistance. diffuse reflectance infrared Fourier transform spectroscopy (CO‐DRIFTS) results reveal that present weak binding ability, reducing intermediate. In addition, Ga‐O‐PtPd‐based Zn‐methanol‐air batteries an excellent activity compared with catalysts.

Electrocatalytic tandem nitrate reduction to ammonia (NO3 --to-NH3) offers a promising pathway for energy and environmental sustainability. Although considerable efforts have been presented modulate the reaction pathways enhanced NO3 --to-NH3 electrocatalysis, these advances often require relatively high overpotentials balance yield rate selectivity of NH3, resulting in remarkable inefficiency. Inspired by enzyme catalysis nature, herein enzyme-like electrocatalyst is designed consisting core Cu2O/Cu heterojunction surrounded mesoporous PdCu shell (Cu2O/Cu@mesoPdCu) that accelerated electrocatalysis positive potentials. Impressively, Cu2O/Cu@mesoPdCu nanozymes hold superior performance robust NH3 electrosynthesis fairly potential 0.10 V (versus reversible hydrogen electrode), having Faraday efficiency 96.2%, 13.3 mg h-1 mg-1, half-cell 46.0%. Kinetic studies, situ spectra density functional theory calculations revealed preferentially adsorbed - further reduced *NO2, while active radicals enriched on promoted multistep hydrodeoxygenation *NO2 within "semi-closed" microenvironment, both which synergistically enabled Moreover, this disclosed better more energy-efficient manner when coupling with thermodynamically favorable ethanol oxidation reaction.
