Abstract:
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.
