Use of CO as a cleaning tool of highly active surfaces in contact with ionic liquids. Ni deposition on Pt(111) surfaces in IL

This work proposes a pretreatment strategy of a flame-annealed Pt(111) single crystal ensuring surface ordering and avoiding surface contamination for experiments in ionic liquid (IL) media,. A room temperature ionic liquid (RTIL) and a Deep Eutectic Solvent (DES) representative of two families of i...

A room temperature ionic liquid (RTIL) and a Deep Eutectic Solvent (DES) representative of two families of ionic liquids were selected as test electrolytes: The RTIL used was the 1-ethyl-2,3-dimethylimidazolium bis(trifluoromethyl)sulfonylimide ([Emmim][Tf2N]) and the DES was based on the eutectic mixture of choline chloride (ChCl) and urea (1ChCl:2urea molar ratio).
