Description 614-619
Tailoring the morphological features of nanomaterials is of great importance for varied applications in energy storage,
environment remediation etc. but is hampered by different parameters. Herein, a novel step by step synthesis approach is
reported to elucidate different morphology of MoS2 heterostructures. A solvothermal method is employed to synthesize
molybdenum glycerate (MoG) solid spheres (SS) followed by subsequent sulphidation. Continuous sulphidation of 3 hours
and 8 hours produces flowers and ball-in-ball MoS2 heterostructures respectively. FESEM micrographs show the formation
of MoG SS and different MoS2 heterostructures. XRD, Raman and UV measurements confirm the phase transition from 2H
(semiconductor) to 1T (metallic) phase in 8 hours sulphidated ball-in-ball heterostructure. The formation of ball-in-ball
morphology is attributed to the Kirkendall effect. The findings could potentially be extended to the idea of phase transitions
and their applications.
