Economic Low‐Carbon Chemical Production via Paired Electrolysis of Carbon Monoxide (CO) and 5‐hydroxymethylfurfural (HMF)

open access: yesAdvanced Materials, EarlyView.
Replacing CO2 with CO at the cathode and integrating a catholyte‐layer membrane electrode assembly transforms paired electrolysis into a stable platform for co‐producing ethylene and 2,5‐furandicarboxylic acid. Combined experimental and techno‐economic analyses identify carbon monoxide and 5‐hydroxymethylfurfural as the most compatible pairing ...

Co1/Ru Single‐Atom Alloy Catalyst for Sustainable Polypropylene Hydrogenolysis to Long‐Chain Liquid Products

open access: yesAdvanced Materials, EarlyView.
A titania‐supported Co1/Ru single‐atom alloy catalyst enables efficient polypropylene hydrogenolysis. Ru─Co─Ru motifs maintain Ru activity while suppressing excessive chain scission to gaseous products. Both virgin and waste plastics achieve high, environmentally and economically optimal C11+ liquid yields, supporting sustainable chemical recycling ...
