HETEROGENEOUS CATALYSIS RESEARCH
The nanoscale chemical reactions occurring at the surface of catalysts can drastically alter the performance and reliability of those catalysts. 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 catalyst performance.
GAS-PHASE CATALYTIC REACTIONS – ATMOSPHERE AX
Apply high temperatures in pressurized, gaseous environments to understand catalyst behavior
Observe structure-function relationships at atomic resolution by observing catalysts in their relevant environments over time complemented by residual gas analysis with a uniquely integrated mass spectrometer.

ELECTROCATALYSTS IN A LIQUID ENVIRONMENT – POSEIDON AX AND TRITON AX
Perform classic electrochemical analyses in a liquid electrolyte within the TEM
Observe the mechanisms that lead to a loss in activity, selectivity, and lifetime of the catalyst for known and new catalyst materials. Perform temperature-controlled electrochemical studies with Triton AX and room temperature electrochemical studies with Poseidon AX.
