Abstract
Scanning electrochemical microscopy (SECM) is a type of scanning probe microscopy, which can not only provide the topographical information, but also offer the electrochemical properties of different samples. The interrelationship of physical and electrochemical properties of a sample can be searched at a high-resolution scale due to the introduction of ultramicroelectrode (UME). With the continuous development of modern nanotechnology, the SECM probe has been improved with drastically decreasing its size down to nanometer. Meanwhile, to evaluate and understand the electrochemical performance of various electrocatalysts for both oxygen and hydrogen reactions with high-efficiency is highly demanded in the research area of green new energy conversion and storage systems, such as regenerative fuel cells and rechargeable metal-air batteries. Therefore, this review will provide a snapshot in the preparations and developments for different types of nanoprobes of SECM. The recent advances in applications of nanoscale SECM in studies of electrocatalysts for both oxygen and hydrogen reactions are also summarized. Finally, some prospects for the future development of nanoscale SECM are discussed.
