Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

Chemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.

Critical mineral removal from mining‐impacted waters using microalgal biomass

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Rising demand for critical minerals has led to increased mining and mineral processing activities, resulting in the release of metal‐contaminated waters requiring treatment. Conventional treatment methods, such as lime neutralization, effectively precipitate metals; however, they are less effective at low metal concentrations and produce large

Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

A Self‐Enhanced Tandem Catalytic System for Olefin‐to‐Diol Conversion Powered by Single‐Atom Fe Catalysts With In Situ Generated Acid

EcoEnergy, EarlyView.
A single‐atom iron catalyst with well‐defined Fe–N4 sites enables a tandem epoxidation‐hydrolysis process for converting terminal olefins to 1,2‐diols. The in situ‐generated isobutyric acid drives the hydrolysis step, affording broad substrate scope and excellent recyclability.
