Eugenol Hydrodeoxygenation Over Mixed Mo−W Carbides

open access: yesChemSusChem
AbstractThe modification of molybdenum carbide catalysts by another transition metal has raised an increasing research interest due to the significant improvement of catalyst activity in hydrodeoxygenation of lignin derivatives. At par with the commonly used Co and Ni that add a strong hydrogenation functionality, it was found that the addition of the ...

Catalytic Upgrading of Biomass Model Compounds: Novel Approaches and Lessons Learnt from Traditional Hydrodeoxygenation – a Review

open access: yesChemCatChem, 2019
Catalytic hydrodeoxygenation (HDO) is a fundamental process for bio‐resources upgrading to produce transportation fuels or added value chemicals. The bottleneck of this technology to be implemented at commercial scale is its dependence on high pressure ...

Nitrogen‐Rich, Tröger's Base‐Linked Porous Organic Polymers (POPs) as Heterogeneous Catalysts and Adsorbents of Organic Pollutants From Water

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 3, January 15, 2026.
Synthesized Tröger's based POPs showed great versatility in heterogeneous catalysis reactions and for pollutant adsorption. ABSTRACT Porous organic polymers are a new class of polymeric materials that combine permanent porosity, high surface area, monomer diversity, and synthetic tunability, making them highly promising candidates for application in ...

Computational Characterization of the Energetics, Structure, and Spectroscopy of Biofuel Precursors: The Case of Furfural‐Acetone‐Furfural

open access: yesJournal of Computational Chemistry, Volume 47, Issue 1, 05 January 2026.
First‐principles computational characterization of the furfural‐acetone‐furfural adduct from structural motif and conformers to vibrational and electronic spectra. ABSTRACT Using density functional theory, we identify the 30 low‐lying structures of the furfural‐acetone‐furfural adduct, a valuable biofuel precursor.

Valorisation of lignin – Achievements of the LignoValue project [PDF]

open access: yes
Lignocellulosic biorefinery for production of biofuels, materials and chemicals requires valorization of all fractions including lignin. As a consequence of its poly-aromatic structure, lignin potentially serves as a source for aromatic chemicals.

Strong Metal‐Support Interactions on TiO2‐Supported Metal Catalysts for Fine‐Tuning Catalysis

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 1, 2 January 2026.
This review offers an in‐depth overview and guide to the origin, modulation, and dynamics of strong metal‐support interaction (SMSI) in TiO2‐based catalysts for optimizing catalysis. It explores the functions of oxygen vacancies, surface/alloy formation energies, and TiO2 structural/thermal aspects.
