One-pot facile synthesis of rod-like Bi2S3 particles in deep eutectic solvent and their ppb-level selective H2S gas detection†
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.
