Shape control of colloidal metal nanocrystals

WebbShape-controlled synthesis is one of the fundamental questions in nanoscience. The performances of nanomaterials are usually closely related to their morphology. For the MHP NCs, the most frequently reported morphologies of the CsPbX 3 NCs are cubic or polyhedral shapes. WebbThis “precursor concept’’ for the manufacture of solid metal colloid catalysts was already proposed by H. Bönnemann in the 1990s [10]. Compared to conventional salt …
