Superior CO2 Conversion Performance by Er‐Doped BiOCl Nanosheets Through Synergistic Photocatalytic Memory Effect and Er‐Doping

Carbon Energy, EarlyView.
Er‐doping and the photocatalytic memory effect through visible‐light irradiation synergistically reconstruct internal electronic states of ultrathin Er‐doped BiOCl nanosheets and generate stable oxygen vacancies. Light absorption, charge carrier separation, and CO2 adsorption capability are subsequently enhanced, leading to a significant increase in ...

Ruthenium‐Titania Interface‐Mediated Water Activation for High Turnover Frequency in Alkaline Hydrogen Evolution

Carbon Energy, EarlyView.
Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...

Fe Atoms Accelerator Coupled With Oxygen Vacancies Channel Synergistically Boost OER Performance of Fe‐CoMoO4‐Ov Nanosheets

Carbon Energy, EarlyView.
Fe‐CoMoO4‐Ov/NF demonstrates significantly improved OER catalytic performance compared to CoMoO4. Specifically, the introduced Fe atoms act as a promoter for surface reconstruction, significantly reducing the energy required for surface reconstruction to generate FeCoOOH. The oxygen vacancies serve as electron channels between the core Fe‐CoMoO4‐Ov and

In situ Generation of Fluoride Catalysts for CO2‐to‐Formic Acid Conversion With Silicon Reducing Agent

Chemistry – A European Journal, EarlyView.
Reductive conversion of CO2 to formic acid with waste silicon reducing agent catalyzed by in situ generation of active fluoride species from a tertiary amine, protonic acid, and simple inorganic fluoride salt, such as KF and NaF. ABSTRACT The activation and catalytic reduction of carbon dioxide (CO2) using silicon‐based reducing agents is an important ...

Carbonate- and silicate-metasomatized mantle beneath Himalayan-Tibetan orogenic belt

Communications Earth & Environment
The extreme geochemical enrichment of post-collisional potassium-rich lava in the Alpine-Himalayan orogenic belt has led researchers to hypothesize that enrichment is inherited from a metasomatized mantle source potentially incorporating crustal ...

Cation‐Directed Host–Guest Assembly and Reversible Wheel to Cluster Interconversion in a 20‐Molybdate System

Chemistry – A European Journal, EarlyView.
The polyoxo‐20‐molybdate(VI) wheel [MoVI20O60{AsO2(CH3)2}12]12− (Mo20) can be prepared with or without a central guest in a controlled, cation‐directed fashion. When Mo20 is dissolved in water, it exhibits an immediate, quantitative, and fully reversible solution transformation to a tetranuclear Mo4 cluster, which transforms in the solid state again to

The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, EarlyView.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

Growth and Nitrogen Fixation in Silicon and/or Potassium Fed Chickpeas Grown under Drought and Well Watered Conditions [PDF]

Journal of Stress Physiology & Biochemistry, 2013
A pot experiment was conducted to study the effects of silicon (Si) and/or potassium (K) on plant growth, nitrogen uptake and N2-fixation in water stressed (FC1) and well watered (FC2) chickpea plants using 15N and 13C isotopes. Three fertilizer rates of

Silica‐Supported Mononuclear Methyl‐Platinum Complexes Stabilized by Trimethylphosphine—Synthesis, Structure, and Reactions Under Reducing Conditions

Chemistry – A European Journal, EarlyView.
The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...
