The synthesis of hollow CuInS2 microspheres with hierarchical structures

Hollow CuInS 2 microspheres with hierarchical structures were synthesized via solution-based method. The detailed HRTEM and XRD results demonstrated the presence of zincblende CuInS 2 microspheres trunks and wurtzite nanobelts attached onto the microspheres. As it was found, oxygen had decisive effect on the formation of CuInS 2 microspheres. Detailed investigation indicated the growth of hierarchical structured CuInS 2 microspheres simultaneously underwent two different mechanisms, phase transformation for zincblende CuInS 2 microspheres and catalytic growth for wurtzite CuInS 2 nanobelts.
