Graphene is a promising next-generation conducting material with the potential to replace traditional electrode materials in supercapacitors. Since energy storage supercapacitors relies on electrolyte-electrode interface, here we elucidate interfacial subnanometer structure of single component liquid composed solely cations and anions - an ionic liquid- electrified graphene. We study effect applied interaction between graphene silicon tip describe it within framework...
A barrier to understanding the factors driving catalysis in oxygen evolution reaction (OER) is multiple overlapping redox transitions OER catalysts. The complexity of these obscure relationship between coverage adsorbates and kinetics, leading an experimental challenge measuring activity descriptors, such as binding energies, well adsorbate interactions, which may destabilize intermediates modulate their energies. Herein, we utilize a newly designed optical spectroelectrochemistry system...
Repeatedly applied nanoconfinement of [HMIM] EtSO<sub>4</sub> between mica surfaces induces a long-range liquid-to-solid transition that remains after confinement has been removed.
Rhodium single-atoms on carbon nitride are robust and efficient catalysts for the hydroformylation of styrene. Experimental analyses DFT calculations confirm isolated nature Rh atoms their robustness as catalysts.
Structural forces reveal the ordered structure of one ionic liquid at rough interfaces well-defined nanoscale roughness, also under nanoconfinement.
With reference to our previous surface-force study on 1-hexyl-3-methylimidazolium ethylsulfate ([HMIM] EtSO4) using an extended surface forces apparatus, which showed ordered structure within the nanoconfined dry ionic liquid (IL) between mica surfaces that up ∼60 nm from surface, this work focuses influence of environmental humidity bulk, interfacial and [HMIM] EtSO4. Infrared spectroscopy rheometry reflect changes in chemical physical properties bulk IL due uptake water when exposed...
Abstract The development of highly efficient and selective catalysts for carbonylation reactions represents a significant challenge in catalysis. Single‐atom (SACs) have postulated as promising candidates able to combine the strengths both homogeneous heterogeneous catalysts. In this paper, we review recent advances tailoring solid supports SACs enhance their catalytic performance reactions. We first discuss effect on hydroformylation reaction catalysed by SACs, followed methanol, ethanol,...
A conventional Pt/CeO2/Al2O3 catalyst physically mixed with an ionic conductor (Mo- or Eu-doped ZrO2) was tested at high space velocity (20,000 h−1 and 80 L gcat−1) under model conditions (only CO H2O) industrial conditions, a realistic feed. The promoted system the showed better catalytic activity associated water dissociation mobility, considered as rate-determining step. activation assessed by operando diffuse reflectance infrared fourier transformed spectroscopy (DRIFTS) studies reaction...
Catalytic structuration on SiC extrudates improves the catalytic performance of Ni based catalysts in toluene reforming, and provides promising materials for hot gas cleaning biomass gasification.
Three Ni-based catalysts (Ni/CY, Ni/LSCF and RuNi/LSCF) were submitted to a pre-treatment in gas atmosphere generated during biomass gasification process. The modifications of the physicochemical properties catalytic performance pre-treated model ex-biomass compared with H2. generation Ni0 through was evidenced. This also provoked formation whisker carbon deposits at surface change Ni dispersion by comparing reduction WGS, CO methanation toluene reforming evaluated. Both exhibited activity...
