Hierarchical nanostructures of nitrogen-doped molybdenum sulphide for supercapacitors.

ABSTRACT: Flower-like nanostructures of molybdenum disulphide (MoS₂) have been effectively synthesised by the hydrothermal method and further doped with nitrogen using varying concentrations of urea. The formed hierarchical nanostructures are characterised by spectroscopy as well as electrochemical techniques. The structural analysis confirms the formation of a hexagonal MoS₂ crystal structure. The existence of MoO₂/MoO₃/MoS₂ composites is also observed after heating MoS₂ with a lower urea concentration. Surface morphological analysis of all the prepared compositions shows the appearance of flower-like nanostructures formed by the stacking of 20-80 nanosheets to create individual flower petals. Nitrogen doping shows enhancement in the
