Ionic Liquid-Supported TEMPO/Polymeric Ionic-Liquid/Carbon Black Ternary Composite: Preparations and Applications in Electrochemical Oxidation of Alcohols
摘要
Abstract
To effectively recover redox catalyst and supporting electrolyte,a novel ternary composite consisting of ionic liquidsupported TEMPO,polymeric ionic-liquid and carbon black was prepared.The ionic-liquid supported redox catalyst TEMPO-IL-BF4 was firstly synthesized from 4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl,and followed by the reaction of polydimethy ldiallylammonium chloride (PDDA) and bis(trifluoromethane)sulfonimide lithium salt (LiTFSI) to form poly[diallyldimethylammoniumbis(trifluoromethanesulfonyl)imide] (PDDA(rf2N)).A combination of the above mentioned two synthesized materials and carbon black afforded to obtain the ternary composite,which was used as the recoverable supporting electrolyte and mediator for the electrochemical oxidation of alcohol.The results indicate that various alcohols could be oxidized efficiently to the corresponding aldehydes or ketones with the more than 80％ yields in the presence of the ternary composite under electrochemical conditions.In addition,the composite could be recovered with 95％ recovery yield after being used for 4 times in experiments.The development of the ternary composite provides an efficient and sustainable approach for the recovery of supporting electrolyte and redox catalyst.关键词
