|Title:||Perpendicular branching in crystal growth of 3D architecture-tuned cadmium hydroxide arrays: From oriented tripods to faceted crystals|

|Abstract:||A new surfactant-free crystal growth process to prepare perpendicularly branched tripods, through heterogeneous nucleation and anisotropic growth on substrates using a chemical liquid-phase deposition technique, was developed. A piece of cadmium foil was put in formamide aqueous solution followed by purging with oxygen and further heating at 65°C for a few days. The thermal decomposition of cadmium hydroxide tripods at a higher temperature of 600°C led to the formation of nanoparticles-built architecture with a retained contour of tripod arrays. The results also show that cadmium hydroxide crystals can be easily transformed into cadmium carbonate crystals through reaction with CO 2. In the absence of formamide, the dissolution of cadmium carbonate crystals is observed due to a hindered release of cadmium ions into pure water.|
