A thorough comprehension of the mechanism behind organic electrooxidation is crucial for development efficient energy conversion technology. Here, we find that trivalent nickel capable oxidizing organics through a nucleophilic attack and electron transfer via nonredox process. This exhibits exceptional kinetic efficiency in possess highest occupied molecular orbital levels ranging from -7.4 to -6 eV (vs. Vacuum level) dual local softness values atoms functional groups, such as hydroxyls...
Abstract Compressive strain, downshifting the d -band center of transition metal oxides, is an effective way to accelerate sluggish kinetics oxygen evolution reaction (OER) for water electrolysis. Here, we find that anisotropic thermal expansion can produce compressive strains IrO 6 octahedron in Sr 2 4 catalyst, thus its d- band center. Different from previous strategies create constant crystals, thermal-triggered be real-timely tuned by varying temperature. As a result strain accelerating...
The comprehension of activity and selectivity origins the electrooxidation organics is a crucial knot for development highly efficient energy conversion system that can produce value-added chemicals on both anode cathode. Here, we find potential-retaining trivalent nickel in NiOOH (Fermi level, −7.4 eV) capable selectively oxidizing various primary alcohols to carboxylic acids through nucleophilic attack nonredox electron transfer process. This (methanol, ethanol, propanol, butanol, benzyl...
Substantial overpotentials and insufficient unstable active sites of oxygen evolution reaction (OER) electrocatalysts limit their efficiency stability in OER-related energy conversion storage technologies. Here, a template editing strategy is proposed to graft highly catalytic species onto conductive rigid frameworks tackle this challenge. As successful attempt, two types NiO6 units layered Ni BDC (BDC stands for 1,4-benzenedicarboxylic acid) metal organic are selectively edited by chemical...
IrO x /Ni(OH) 2 with reagent-adaptive active sites can switch between urea oxidation and oxygen evolution depending on reagent coverage to adapt the reaction environment, which is useful for hydrogen production environmental purification; a promising approach adaptable catalysis.
Stability and antipoisoning effects are the main challenges for application of commercial Pt/C catalysts. Herein, we soaked adsorbed polydopamine to coat Pt particles on subsequently converted coatings few-layer N-doped graphene by calcination produce Pt/C@NC. The effectively block direct contact nanoparticles electrolyte, thus enhancing catalyst stability avoiding Ostwald ripening suppressing competitive adsorption toxicants, contributing enhancement ability. More importantly, do not hurt...
To explore the effects of acute paraquat (PQ) exposure on phenotypic polarization hippocampal microglia and its mechanism. An PQ rat model was established. Male SD rats were exposed to 0, 5, 25, 50 mg/kg PQ, brain tissue collected after 1, 3, 7 days exposure, respectively. Hippocampal pathological changes examined by H&E staining, immunohistochemistry (IHC) used detect in number Iba-1-positive cells, average endpoints, process length. The protein expression Iba-1 detected western blotting....
High-energy-density fuels from carbon dioxide reduction are an ideal medium to store intermittent renewables. Lewis pairs highly active for activation of small molecules. A challenge is create electrochemically stable on electrodes exploit small-molecule activation. Here, a strategy protonating surface oxidation layer oxytropic alloys proposed by coordinatively unsaturated metal sites (Lewis acids) and hydroxyls bases). We find that the element electronegativity metal-hydroxyl stability...
Ozone pollution has been associated with several adverse effects, including memory impairment, intellectual retardation, emotional disturbances. However, the potential mechanisms remain uncertain. The present study aimed to investigate whether ozone (O3) regulates synaptic plasticity through PI3K/Akt/GSK3β signaling pathway and induces neurobehavioral modifications among young rats. In vivo, newborn rats were used construct animal model of early postnatal O3 treatment. vitro, this measured...
The sluggish kinetics of CO2 activation and reduction severely limit the energy conversion efficiency electrocatalytic into fuels. Here, ZnSn(OH)6 with an alternating arrangement Zn(OH)6 Sn(OH)6 octahedral units SrSn(OH)6 SrO6 were adopted to check effects frustrated Lewis pairs (FLPs) on electrochemical reduction. FLPs in situ electrochemically reconstructed by reducing unstable Sn-OH Sn-oxygen vacancies (Sn-OVs) as a acid site, which are able create strong interactions adjacent stable...
Strategies to efficiently activate CO 2 by strongly inhibiting the competitive hydrogen evolution reaction process are highly desired for practical applications of electrochemical reduction technique.
Stability is the main challenge for application of PtCo catalysts because Co tends to leach during electrochemical reaction. Herein, we immerse and adsorb dopamine densely coat Pt
