The Heterogeneous Catalysis Unit provides support to ICIQ researchers working on heterogeneous catalysis (gas phase reactions catalysed by solids).
To this purpose, it comprises equipment for a wide catalyst characterisation and testing, including textural and reactivity studies, performance of the catalysts for different reactions at different operating conditions and mechanism elucidation of catalytic processes.

The following techniques are available:
• Physisorption for solids textural characterization (porous structure).
• Chemisorption
• Helium pycnometry for the real density of solids.
• Temperature programmed reaction (TPD/TPR/TPO, pulse chemisorption) for surface reactivity studies.
• Steady state catalytic activity studies in a fixed bed reactor.
• Reactor TAP for the elucidation of reaction mechanisms.
• MS and GC for the on line analysis of gas streams and atmospheres.
• Dynamic Light Scattering (DLS) for the measurement of hydrodynamic size and zeta potential of nanoparticles and macromolecules in suspension.
