Ultra-fast BCDI during acetylene hydrogenation of Pd nanoparticles

The aim of this project is to investigate the effect of the Pd surface structure on the catalytic performance during acetylene (C2H2) hydrogenation at room temperature. Open questions remain regarding the mechanism and the kinetics of acetylene adsorption and desorption on the different Miller indexed surfaces of Pd [1]. Using ultra-fast and stroboscopic Bragg coherent x-ray diffraction imaging (BCDI), we intend to map in situ and operando, the three-dimensional evolution of the deformation/strain field of multi-faceted Pd nano-crystallites. This will yield the mechanistic-structural picture at second (ultra-fast rocking-curve) and millisecond (stroboscopic mode) timescales
