Molecular structures of ten ionic hydrogen bond-mediated anhydrous tert-butylammonium salts from different carboxylic acids

A natural deep eutectic solvent-based aqueous biphasic system coupled with MoS2 photocatalytic reduction for green recovery of gold from thiosulfate solution

“…This indirectly affects the stretching vibration of –CO in Lac. 43 In addition, we also observed that the vibration stretching peak of –C–N at 1088.15 cm −1 without gold red-shifted to 1086.45 cm −1 when it was loaded with gold. 44 The possible reason is that after the Cl − anions in ChCl-Lac were replaced by Au(S 2 O 3 ) 2 3− anions, which have a high negative charge, the electrostatic attraction between Au(S 2 O 3 ) 2 3− and N + is enhanced.…”
