From etched to engineered: Confining ruthenium in MXene interlayers for site-controlled hydrogenolysis

Hydrogenolysis is promising for converting polyolefins into liquid hydrocarbons, but catalysts suffer from limited polymer accessibility and excessive methane formation. In this work, Kamali et al. confined Ru within MXene layers, enhancing polymer access to active sites and steering reaction selectivity toward more valuable products at a higher reaction rate.
