Transmission electron microscopy (TEM) has the necessary resolution and flexibility to characterize catalysts at magnifications spanning five orders of magnitude, from micrometer- to atomic-level, via imaging, electron diffraction and spectroscopy. It can provide detailed structural information of catalysts, e.g., particle size distributions, shape of metal NPs, composition of NP surfaces, surface structure, crystal structure. With the analytical accessories of energy-dispersive X-ray spectroscopy (EDX) and electron energy loss spectroscopy (EELS), chemical information can be examined at the atomic scale. Combined with in situ techniques, it even enables scientists to characterize the structure changes of the catalysts during reaction in gas or liquid phase. My research focuses on using high resolution TEM (HR-TEM) and in situ TEM to study supported catalysts at atomic- and nanometer- scale.
