A fixed-bed reactor has been designed and constructed for ex situ transmission electron microscopy (TEM) studies of heterogeneous catalysts. The ex situ facility exposes a fully prepared TEM sample on a grid to actual process conditions (e.g., temperature, pressure, gas composition, etc.) by placing the grid at the exit section of a conventional fixed-bed reactor. A unique reactor design allows grid transfer into the electron microscope and back into the reactor again under a controlled (inert) environment, thus allowing time-resolved monitoring of catalyst morphology changes under realistic, well-controlled conditions. This facility stands completely independent of the TEM. Thus, no special TEM modifications are required and long-term ex situ studies do not impact microscope utilization. The utility of the facility is demonstrated via the oxidation of intermediate size (∼20–∼80 nm) supported copper particles.

Ex situ transmission electron microscopy: a fixed-bed reactor approach.

Nucleation and growth of metal particles on oxide surface is of theoretical and practical interest. Ni film has been grown on MgO [1], but its growth behavior at early stage has never been studied. In the present work, the nucleation and growth of epitaxial nanosized Ni particles on MgO (001) surface was investigated by in situ transmission electron microscopy (TEM). A hexagonal closepacked (hcp) structure of element Ni was discovered and its subsequent transition to face centered cubic (fcc) structure was observed.[2]
