Harnessing Interfacial Cl− Ions for Concurrent Formate Production at Industrial Level via CO2 Reduction and Methanol Oxidation

Advanced Functional Materials, EarlyView.
The replacement of the anodic OER in CO2RR with energy‐saving methanol oxidation reaction and the creation of a favorable microenvironment through interfacial Cl− ions enable concurrent formate production at industrial‐level current densities. Abstract The efficient electrocatalytic conversion of CO2 to formate is often impeded by the high energy ...

Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

Advanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Substrate Engineering for Durable Omniphobic Liquid‐Like Surfaces

Advanced Functional Materials, EarlyView.
The significant yet less investigated role of substrates in determining the liquid‐repellency and mechanical durability of liquid‐like surfaces (LLSs) is explored. Thick and crack‐free sol–gel silica intermediary layers are developed that can smoothen substrate asperity roughness even at the micron scale, enabling omniphobic polydimethylsiloxane‐based ...

Second hydrogen atom abstraction by molecular ions [PDF]

Journal of Mass Spectrometry, 2017
We report the observation of a new physical phenomenon of the addition of 2 hydrogen atoms to molecular ions thus forming [M + 2H]+ ions. We demonstrate such second hydrogen atom abstraction onto the molecular ions of pentaerythritol and trinitrotoluene (TNT). We used both gas chromatography mass spectrometry (GC‐MS) with supersonic molecular beam (SMB)

Radiation Abstraction of Hydrogen Atoms in Single Crystals of Thymine

The Journal of Chemical Physics, 1972
Single crystals of both thymine monohydrate and anhydrous thymine were irradiated at 77°K and the radicals induced were analyzed with ESR spectroscopy. The radical species, formed by abstraction of a hydrogen atom from nitrogen, was studied in detail. Molecular orbital calculations suggest that the abstraction takes place from N(1).

Hydrogen Abstraction from the Hydrazine Molecule by an Oxygen Atom

The Journal of Physical Chemistry A, 2014
Thermochemical and kinetics properties of the hydrogen abstraction from the hydrazine molecule (N2H4) by an oxygen atom were computed using high-level ab initio methods and the M06-2X DFT functional with aug-cc-pVXZ (X = T, Q) and maug-cc-pVTZ basis sets, respectively.

Kinetics of Hydrogen Abstraction Reactions of Methyl Palmitate and Octadecane by Hydrogen Atoms

The Journal of Physical Chemistry A, 2019
Hydrogen abstractions play a crucial role in the consumption of fuel molecules during fuel pyrolysis and combustion processes. In this study, a generalized energy-based fragmentation approach was used to obtain CCSD(T)-F12a/cc-pVTZ energy barriers of hydrogen abstraction reactions by hydrogen atoms from methyl palmitate (C15H31COOCH3), a key component ...
