Silica-assisted mesoporous Co@Carbon nanoplates derived from ZIF-67 crystals and their enhanced catalytic activity

Silica-assisted CoOx@CS nanocomposites exhibit mesopores characteristic, nanoplates and basicity, showing higher activity than that of CoOx@C nanocomposites (obtained via a direct pyrolysis of ZIF-67 crystals) in ammonia decomposition reaction.205
