Bifunctional Reduced Graphene Oxide Derivatives for PFOA Adsorption

ChemistryEurope, EarlyView.
A bifunctional graphene‐based material is developed for selective PFAS adsorption from water. Thermally reduced graphene oxide is modified with quaternary ammonium groups and fluorinated chains, promoting electrostatic and fluorine–fluorine interactions. Surface functionality is characterized by X‐ray photoelectron spectroscopy, atomic force microscopy,

Carbon‐Supported Dual‐Nickel Atom Catalysts With Stabilized Ni─N3 Active Sites for Efficient CO2 Electroreduction

Carbon Energy, EarlyView.
Dual‐nickel atom catalysts (Ni‐DACs) are developed to stabilize unsaturated Ni─N3 atomic sites by constructing N3Ni─NiN3 dual‐atom structures from coal. Benefiting from the modulated electronic structure that optimizes intermediate adsorption, Ni‐DACs outperform Ni‐SACs in CO2 electroreduction, achieving a max FECO of 98.6% at −0.8 V vs RHE and a TOF ...

Boosting Electron‐Hole Charge Separation in CO2 Photoreduction through Fluoroporphyrin‐Linked Nickel(II)‐Acetylide Frameworks

Carbon Energy, EarlyView.
A NiII‐acetylide framework, H2TFPP‐Ni‐AF, demonstrates outstanding photocatalytic CO2 reduction performance: 13.16 mmol h−1 g−1 of CO with 97.9% selectivity. Synergistic interactions, including d‐p orbital hybridization within NiII‐bis(acetylide) moieties ( − C ≡ C−NiII(PBu3)2 − C ≡ C − ) and the efficient charge transport afforded by π‐conjugated ...

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...

Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.
