Rich‐Electronic Interface Promoting Hydrogen‐Bond Reversible Formation for Ultra‐Stable and Energy‐Efficient Catalytic CO2 Capture

open access: yesCarbon Energy, EarlyView.
Bridging micro–macro scales, a biomass‐derived Ni@C interface creates electron‐rich sites and hydrogen‐bond proton‐relay pathways, tuning interfacial charge and reversible hydrogen bond to enhance carbon capture capacity. Verified by in situ spectroscopy, multi‐scale simulations, and long‐term industrial testing, this system enables low‐temperature and

Strongly‐Anchored Ionomer‐Free Anode Catalyst Layer Fabricated via Joule Heating Achieves Efficient Electron/Mass Transfer for Acidic Water Electrolysis

open access: yesCarbon Energy, EarlyView.
An ionomer‐free anode catalyst layer is fabricated via rapid Joule heating, partially embedding IrO2 nanoparticles into the membrane to form a robust, anchored interface. This architecture eliminates ionomer‐induced poisoning and mass‐transport barriers, enabling efficient water‐mediated proton transport and electronic connectivity.

Oxidation of Allylic Alcohols by Manganese Oxides: Elucidating the Influences of MnOx Structure and Mn Oxidation State on Reactivity

open access: yesChemistry – A European Journal, EarlyView.
Manganese oxides (MnOX) of different structures and with different Mn oxidation states exhibit significant variation in their reactivity toward the oxidation of allylic alcohols. Using two allylic alcohol model substrates, we demonstrate the relationship between activity and MnOX structure, Mn4+ content and incorporated secondary cations.

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

open access: yesChemistry – A European Journal, EarlyView.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Ru Nanoparticle Supported by Mesoporous SiOx and Pillared Montmorillonite: Suppressing Catalyst Inhibition in Carbon Dioxide Hydrogenation

open access: yesChemistry – A European Journal, EarlyView.
Ru nanoparticles confined within mesoporous SiOx‐pillared montmorillonite exhibit exceptional performance for CO2 methanation. The catalyst maintains a high reaction rate even at elevated CO2 conversion while preserving high Ru mass–specific activity, overcoming typical inhibition by H2O and CO observed in conventional supported Ru catalysts.

Embedding a Dinuclear Ru─Pt Photocatalyst Into Polyampholytic Graft Copolymer Matrix Enables Prolonged Hydrogen Evolution While Allowing Catalyst Repair

open access: yesChemistry – A European Journal, EarlyView.
A unimolecular polyampholytic graft copolymer matrix provides a protective confinement for an electrostatically embedded tetrapyridophenazine‐bridged heterodinuclear Ru‐Pt hydrogen evolving photocatalyst. The matrix slows the degradation kinetics of the catalyst and at the same time does not hinder its repair by ammonium persulfate.

Composition of Purified CO2 From Steel Mill Processes—A Classification and Analytical Comparison With Commercial CO2

open access: yesChemie Ingenieur Technik, EarlyView.
Due to the severe catalyst poisoning effect of certain trace components, the purity of CO2 is the main attribute to qualify it as syngas for further downstream processes. This study uses PTR–MS to investigate the trace components of the CO2 produced within the Carbon2Chem project.
