This innovative approach involves the growth of a crystalline (ZIF-67) derived from stable and abundant CoO, resulting in the formation of the composite magnetic CoO@ZIF-67. The synthesis method, based on a solid-state thermal approach (SST), is straightforward and efficient, conducted in a single step and under solvent-free conditions, leading to the homogeneously composite formation of CoO@ZIF-67. Importantly, the composite magnetic CoO@ZIF-67 material has demonstrated remarkable catalytic performance as a heterogeneous catalyst in various reactions while requiring a lower catalyst loading under comparable conditions to those needed for pure ZIF-67. A significant advantage of this newly developed composite catalyst, CoO@ZIF-67, is its ease of separation and recyclability. The recovery catalyst can be achieved through the use of an external magnet, making it a standout feature of the green and environmentally friendly synthetic procedure used in its production.Materials ScienceChemistryPhysics and AstronomyEngineeringSolvent-free synthesis of composite magnetic CoO@ZIF-67 for efficient and practical useArticleSCOPUS10.1016/j.micromeso.2024.1132002-s2.0-85194755794
