Probing multiple Nanocatalysts with various Coherent Diffraction Imaging techniques in Bragg condition

Platinum group metal (PGM) particles are widely used as catalysts in a variety of relevant (electro)catalytic processes. Bragg Coherent Diffraction Imaging (BCDI) is particularly well suited to study strain during catalytic reactions. However, it suffers from two drawbacks: (i) BCDI-probed crystals are typically 10 to 100 orders of magnitude larger than those used commercially, (ii) BCDI studies lack statistical data and often focus on very few crystals. The use of poly-particle BCDI (ppBCDI) and Bragg Ptychography (BP) to map areas containing multiple Pt and Pd nanocatalysts would allow both issues to be addressed and ultimately validate that both techniques, including their data treatments, lead to comparable results.
