Description
Summary:The controlled synthesis of nanomaterials is of prime importance in modern-day science. We report the shape-controlled synthesis of In 2 S 3 spheres via a one-step solvent-mediated method. The process is very economical as it only requires the switching of solvent during synthesis (pure ethylene glycol, ethylene glycol/water, and ethylene glycol/ethanol mixtures) to fabricate porous and hollow In 2 S 3 spheres. We have deliberately chosen a high boiling solvent and a combination of high and low boiling solvents to control the morphology. The synthesized In 2 S 3 hollow spheres proved to be electrocatalytically active for an overall electrocatalytic water splitting and drive the oxygen evolution reactions at 230 mV and the hydrogen evolution reactions at 239 mV to produce a current density of 10 mA cm −2 , respectively.
