摘要
An etching-limited branching growth mechanism has been elucidated during ethanol-assisted solution synthesis of octahedral Cu2O crystals, which is different from the conventional diffusion-limited aggregate and recent overpotential-limited branching mechanism. It provides an innovative approach for revealing the shape evolution from habit formation (octahedron) to branching growth (hexapod-like architecture) via adjusting the competition between preferential growth and selective oxidative etching, and displays a constructive model system for fundamental research of crystal growth and design.
