Inside Cover: Mechanistic Understanding of Efficient Polyethylene Hydrocracking over Two‐Dimensional Platinum‐Anchored Tungsten Trioxide (Angew. Chem. Int. Ed. 40/2023)

Chemical upcycling of high‐density polyethylene at low temperatures remains a significant challenge. In their Research Article (e202305644), Qingyue Wang, Pingwei Liu and co‐workers report a two‐dimensional platinum‐anchored tungsten trioxide catalyst with abundant vacancies and acidic sites that converts polyethylene effectively to fuel. A quasi‐operando spectroscopic study reveals that polymer chains are activated by forming olefinic intermediates, and then hydrocracked by the dissociated hydrogen on two‐dimensional catalyst to form fuel alkanes.
