Electrocatalysts require a hydrated environment along with electrochemical signals to observe their true behavior at the nanoscale. With Protochips’ machine-vision powered suite of in-situ TEM tools you can utilize the electron microscope as a real-time laboratory to study electrocatalysts at a resolution of a few nanometers. In situ TEM enables the study of the oxygen evolution reaction (OER), carbon dioxide reduction reaction (CO2RR), hydrogen evolution reaction (HER), and other conditions at the nanoscale.
