En Route Toward Sustainable Polycarbonates Via Large Cyclic Carbonates
ChemSusChem, Accepted Article.This review reports an up‐to‐date overview of the synthetic methodologies developed for the preparation of large cyclic organic carbonates with ≥ 6‐membered rings (6M‐CCs and above), highlighting the most sustainable synthetic pathways employing diols (including renewable‐based ones) and non‐hazardous carbonyl sources, e.g., linear organic carbonates ...

Intensification of Ethylene Carbonate Synthesis via Microwave‐Induced Phase‐Change Cycles
ChemSusChem, EarlyView.Microwave‐assisted heating under ambient pressure reflux conditions is applied to intensify the transesterification of ethylene glycol with dimethyl carbonate. The proposed method enhances energy efficiency and product yield compared to conventional heating, enabling lower catalyst loading, reduced process time, and significantly decreased energy ...

ChemSusChem, Accepted Article.Plastics are indispensable in daily life, with both production and waste generation increasing annually. As the world strives for net‐zero emissions, advancing plastic recycling technologies has become a global priority. Pyrolytic liquefaction is a promising approach for recovering chemical feedstocks, including fuel fractions, from waste plastics ...

ChemSusChem, EarlyView.Zr8O6‐based metal–organic frameworks (porous coordination network PCN 221 M, M = 2 H, Zn, Ni, ZnNi) with metalloporphyrin linkers are explored for H2 evolution under 405 nm light emitting diode irradiation. PCN 221 Zn exhibits the highest activity with a turnover number (TON) of 4 via dual charge transfer pathways. Spectroscopy revealed Zn‐TCPP acts as

ChemSusChem, EarlyView.The activation of charge redistribution facilitates metal‐to‐metal charge transfer from MnIII to FeIII via the cyanide bridge, stabilizing mixed oxidation states (FeIII/II and MnIII/IV) and thereby enhancing redox stability. This charge redistribution mitigates the Jahn–Teller effect in Mn‐based Prussian blue Analogues, positioning them as promising ...

ChemSusChem, EarlyView.Here, a green synthetic approach through spontaneous adsorption and laccase‐induced reactions is introduced to functionalize lignin nanoparticles (LNPs) with hemicelluloses. The resulting lignin–hemicellulose hybrid nanoparticles presented increase colloidal stability at acidic pH compared to the plain LNPs, encouraging their usage in different areas ...
