Facile Template-free Synthesis of Bi2O2CO3 Flower-like Architectures in Ethylene Glycol–Water System

Abstract A convenient solvothermal route has been developed to synthesize flower-like Bi2O2CO3 architectures. The X-ray diffraction patterns confirm the body-centered tetragonal phase. The SEM and TEM images indicate that the flower-like Bi2O2CO3 architectures are assembled by numerous nanoplates. A self-assembly process is proposed to account for the formation of the obtained hierarchical structures.
