Highly Crystalline and Porous Borocarbonitrides as Metal‐Free Catalysts for Boosted N‐Heterocycle Dehydrogenation

Safe and efficient hydrogen storage is pivotal for enabling a clean hydrogen economy. Liquid organic hydrogen carriers (LOHCs) offer a practical solution, but their deployment is hindered by the lack of highly active and economical dehydrogenation catalysts. Here, we report a metal-free catalyst design that overcomes the long-standing trade-off between crystallinity and surface area in two-dimensional frameworks for highly efficient dehydrogenation of LOHCs.
