Facile preparation of multilayer ultrathin films based on eriochrome black T/NiAl-layered double hydroxide nanosheet, characterization and application in amperometric detection of salicylic acid
A new multilayer ultrathin film (UTF) containing EBT anions and exfoliated nanosheets of Ni–Al LDH was synthesized. The UTF was synthesized by LBL self-assembly technique and its properties were studied by electrochemical method. The UTF modified electrode presented a significant electrocatalytic performance towards the oxidation of salicylic acid.
