Application of Scanning Tunneling Microscopy in Electrocatalysis and Electrochemistry

Scanning tunneling microscopy applications in electrochemistry — beyond imaging

Scanning tunneling microscopy (STM) has gradually matured into a powerful tool for imaging electrode surfaces in the electrochemical environment with atomic resolution. It has been used to elucidate numerous old puzzling structural issues and to reveal many new interesting phenomena. As an imaging tool, it will continue to contribute to the understanding of various electrochemical processes on ...

Scanning Tunneling Spectroscope Use in Electrocatalysis Testing

The relationship between the electrocatalytic properties of an electrode and its ability to transfer electrons between the electrode and a metallic tip in a scanning tunneling microscope (STM) is investigated. The alkaline oxygen evolution reaction (OER) was used as a test reaction with four different metallic glasses, Ni78Si8B14, Ni70Mo20Si5B5, Ni58Co20Si10B12, and Ni25Co50Si15B10, as electrod...

Scanning Tunneling Microscopy

The invention of the scanning tunneling microscope was a singularity event in the field of surface science and condensed matter physics. The ability to visualize individual atoms in an atomic structure was a huge step forward in experimental development, one for which the inventors were awarded the Nobel Prize in Physics in 1986. While a groundbreaking development, the Scanning Tunneling Micros...
