Polydopamine‐Mediated Grafting of Cationic Polymer Brushes for Adsorption of Fluorinated Compounds

open access: yesChemistry – A European Journal, EarlyView.
We introduce a versatile approach to fabricate tunable charged interfaces by functionalizing stonewool fibers with a polydopamine (PDA)–quaternary amine coating via a grafting‐to method. The modified surfaces exhibit rapid, concentration‐dependent adsorption of anionic species driven by electrostatic interactions.

On the Role of Linker Fluorination in the Adsorption‐Induced Structural Response of CeIV‐Based Metal‐Organic Frameworks

open access: yesChemistry – A European Journal, EarlyView.
The effect of the degree of fluorination of the organic linker on the adsorption behavior of MIL‐140A(Ce) is systematically investigated with a combination of experimental techniques. Cooperative adsorption is switched off in less fluorinated frameworks, as a result of reduced steric hindrance around the adsorption sites.

Integration of High‐p, Low‐T CO2 Electrolysis with Pressure Swing Adsorption Purification

open access: yesChemie Ingenieur Technik, EarlyView.
We evaluate a high‐p low‐T CO2 electrolysis (LTCE) cell with a pressure swing adsorption (PSA) to compare cascade vs. recycle operation. Although a cascade yields high CO selectivity but limited yield, a full recycle achieves near‐quantitative CO production, highlighting gas recycling as essential for LTCE/PSA systems.

Innovative electrospun geopolymer/zeolite/PVA composite membranes

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Proposed scheme of gas adsorption mechanisms on electrospun geopolymer/zeolite/PVA composite membranes. Abstract Innovative electrospun poly(vinyl alcohol) (PVA)–geopolymer–zeolite 13X composite membranes were successfully fabricated and systematically characterized.

Boosting Water Vapor‐Assisted Methane Photooxidation Over S‐Scheme MIL‐125‐NH2(Ti)/WO3 Heterojunction Photocatalysts

open access: yesEcoEnergy, EarlyView.
The MIL‐125‐NH2(Ti)/WO3‐x S‐scheme heterostructure was constructed via electrostatic self‐assembly, strategically aligning energy bands to optimize interfacial charge transfer and ·OH generation for C–H activation. The optimized MW‐3 demonstrates exceptional CH4 photooxidation activity using water vapor as a sustainable oxidant, achieving a remarkable ...
