Zeolite catalysts enable sustainable production of biodegradable plastic materials
Dimethoxymethane (DMM) carbonylation provides a mild, green, sustainable route to the production of glycolic acid, a degradable plastic monomer. ZEO-1 zeolite contains a large cage composed of 16×16 and 16×12 MRS crossings, with a small cage composed of high DMM carbonylation activity and a 12×12 MRS crossing section showing high DMM imbalance activity. Zeolite Zeo-1 exhibits both high DMM carbonylation…
