Electrospray deposited Pt film for hydrogen evolution reaction: Effect of solvent solution

▸ Electrospray technique is used for platinum film deposition from different solvent (water, ethanol and mixture of both). ▸ The effect of solvents of different physical properties on film properties is studied. ▸ Hydroxide form of Pt thin film is obtained from water solvent, with low activity for HER. ▸ Pure Pt film is obtained from ethanol solvent with high activity for HER. ▸ Mixed phase is obtained from mixture of both solvent and purity increased with ethanol.
