Characterising 3D Printed Catalytic Structures

Tom Slater

Scientific Case

This is an exploratory study that aims to characterise 3D printed catalytic structures, specifically Pd/C. This catalyst is used for the Suzuki cross-coupling reaction of hydrocarbon fragments and is considered extremely important in organic synthesis ( It is currently performed in batch synthesizers but we believe that by printing structures we can efficiently anchor the catalyst such that we can develop continuous flow reactors.

We wish to characterise using both standard micro and nano-CT the Pd/C structures we have produced. Measurements will be used to assess the fidelity of the printing process including determining the distribution/location of catalyst within structures comparing direct co-printing of support and catalyst with impregnation methods and the impact of firing to the macro and micro-structure. The CT data collected in this study will also act to inform on volumes of interest for subsequent TEM investigations, which will probe the morphology and crystallinity of Pd at the nanometre scale.

Experiment Design

Aim to determine Pd distribution at the micron scale. Subsequent TEM analysis will probe volumes of 500 nm x 500 nm and therefore resolving volumes of this resolution is desirable to identify potential sites.
