▎ 摘  要

In this work, we have developed a new type of sandwiched structured ionic liquid (IL)-carbon nanotube (CNT)-graphene film (GF) synthesized by a facile and effective inkjet printing method. Owing to the synergistic effects of different components in the nanohybrid material, the IL-CNT-GF material demonstrates outstanding properties including large surface area, sufficient surface active sites, and fast charge transferability. When used in electrochemical determination of cadmium ion (Cd2+) and lead ion (Pb2+), it exhibits a good sensing performance of high sensitivity, a wide linear range up to 1 mu M, a low detection limit down to 0.1 nM for Cd2+ and 0.2 nM for Pb2+ (S/N = 3), and good selectivity as well. These outstanding electrochemical sensing performances allow it to be used for heavy metal detection in environment water samples.
