Fund Project: This work was supported by the National Natural Science Foundation of China (No. 20973142), and the NSFC Innovation Group of Interfacial Electrochemistry (No. 21021002), National Project 985 of High Education, New Faculty Starting Package of Xiamen University.

Here we report a novel generation/collection operation mode of scanning electrochemical microscopy, in which a theta micropipette was employed to support two adjacent water/1,2-dichloroethane interfaces separated by the thin central glass wall:one acts as the generator while the other as the collector. The generation current, collection current andcollection efficiencywere enhanced significantly when the tip approached to an insulate substrate.
