Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Entropy‐Stabilized Pd/HEO Bifunctional Catalyst for Selective Aqueous‐Phase Hydrogenolysis of Cellulose to Ethylene Glycol

open access: yesEcoEnergy, EarlyView.
An entropy‐stabilized Pd/HEO catalyst integrates Lewis acid and hydrogenation sites within a robust oxide–metal interface, enabling efficient and selective conversion of cellulose to ethylene glycol (68.3%) in water. ABSTRACT The selective conversion of cellulose into ethylene glycol (EG) under aqueous conditions is an attractive yet challenging route ...
