Efficient Low‐temperature Ammonia Cracking Enabled by Strained Heterostructure Interfaces on Ru‐free Catalyst

Advanced Materials, EarlyView.
Leveraging the strong metal‐support interaction effect, heterostructured interfaces in a Co‐based catalyst are designed to enable low‐temperature ammonia (NH3) decomposition. The induced tensile lattice strain within the core‐shell structure modulates d‐band center of Co, enhancing NH3 adsorption and facilitating N─H bond dissociation. Furthermore, the
