Morphology Evolution and Control of Mo‐polydopamine Coordination Complex from 2D Single Nanopetal to Hierarchical Microflowers

Controllable synthesis of functional materials is of widespread interest for particle engineering. Such a method has not been widely promoted due to the lack of recognition of the fundamental principle, especially for organic–inorganic hybrid materials. Here, as an entrance, the controllable synthesis of Mo‐polydopamine coordination flowers is realized through a facile foaming method, and a 2D nanopetal as the building monomer of the flower is...
