Improving CO2 Photoconversion by Layered Materials: Boosted Optoelectronic Performance and Catalytic Activity of g‐C3N4 by Ultrasound Exfoliation

ChemCatChem, EarlyView.
Exfoliation by ultrasound of graphitic carbon nitride improved activity for the photoreduction of CO2. Abstract Exfoliation of graphitic carbon nitride g‐C3N4 by means of ultrasound (US) treatment at varying input power is investigated. Exfoliation of g‐C3N4 displays a strong dependence of US input power, with a slightly enhanced bandgap (2.8 eV), but ...

Pd Nanoparticles Supported on Activated Carbon and Their Application in the Oxidative Condensation Reaction of Furfural: Effect of Base and Oxidizing Agent on Catalytic Behavior and Deactivation

ChemCatChem, EarlyView.
Catalysts with varying palladium (Pd) loading supported on activated carbon were assessed for their effectiveness in the oxidative condensation of furfural. Furan‐2‐acrolein was the primary product, depending on the palladium content. Reusability tests showed a decline in the yield of furan‐2‐acrolein.

From Biomass to Polymers: Kinetic Analysis and Sustainable Synthesis of Lignin‐Polycaprolactone Copolymers

ChemCatChem, EarlyView.
Lignin‐polycaprolactone (PCL) copolymers were prepared using a highly efficient and nontoxic zinc catalyst. The reaction kinetics were investigated and differ from those usually observed in ring‐opening polymerization. Depending on the chain length of the copolymer, an acceleration of the reaction was found.
