| Abstract Scope |
Bragg Coherent X-ray Diffraction Imaging (BCDI) is a powerful technique enabling three-dimensional nano-scale imaging. Because of unique sensitivity to lattice, BCDI has been employed to visualize morphology as well as internal lattice displacement field of various nano-scaled materials. In-situ/operando capabilities have been added to BCDI for more realistic studies to reveal evolutions of materials while they are under realistic conditions.
In this talk, I will introduce recent experimental results on catalysis observed at the 34-ID-C beamline of the Advanced Photon Source (APS). In-situ/operando BCDI has successfully imaged the evolution and the distribution of strain developed nano-scaled catalysts during catalytic reactions. Different states of strain have been observed depending on catalytic reaction conditions. As diffraction limited storage rings are coming, in-situ/operando BCDI will exhibit more detailed features of nano-scaled catalysts. This talk will introduce some estimates of in-situ/operando BCDI for catalysis studies in the near future. |
