ELECTROCATALYSIS RESEARCH

ELECTROCATALYSIS RESEARCH

With a global focus on more environmentally friendly means of producing energy, electrocatalyst research is at the forefront. With Protochips’ workflow-based in situ TEM solutions, you can utilize the electron microscope to study structure-function relationships that govern the underlying mechanisms dictating electrocatalyst performance. Observe in real-time the oxygen evolution reaction (OER), carbon dioxide reduction reaction (CO2RR), hydrogen evolution reaction (HER), and other reactions critical to the catalyst’s function over time. 

POSEIDON AX AND TRITON AX

Perform classic electrochemical analyses in a liquid electrolyte within the TEM 

Observe the mechanisms that lead to loss in activity, selectivity, and lifetime of the catalyst for both known and new catalyst materials. Perform temperature-controlled electrochemical studies with Triton AX and room temperature electrochemical studies with Poseidon AX.

THE PROTOCHIPS PHILOSOPHY

Each Protochips in situ TEM solution has been designed with three key goals in mind to ensure relevance of the results in a timely fashion.  

Scaling Bulk to Nano

Quantitative measurements with relevant electrode and electrolyte materials create an environment that is most comparable to bulk scale experiments

Accelerating Productivity

Innovative designs and machine vision software lower the learning curve and streamline data collection and analysis

Fostering Collaboration and Discovery

Intuitive data processing platform provides transparency for collaborators, with a new way to visualize data for more productive discussions
