Bismuth sulfide, Bi₂S₃, was prepared by a one-pot reaction using various choline chloride-based deep eutectic solvents (DESs) as the reaction field. Rod-like particles obtained with acetamide–thioacetamide-based DESs were found to exhibit specifically dominant detection properties for H₂S gas, and the gas detection mechanism was discussed by adsorption reaction.
