“…To avoid pollution a more environmentally friendly catalyst is desired. 2,3 Room temperature ionic liquid (IL) systems have many unique properties such as a very large liquid temperature range, and they can be made task-specic for certain applications, 4 which include use as solvents in chemical synthesis and catalysis [5][6][7][8][9][10][11] and separation technology, 12,13 as electrolytes in electrochemical devices, [14][15][16] and as lubricants or as heat-transfer uids. 17 In addition, there is a huge range of possible combinations of cations and anions, which contribute to the design of ILs.…”
