Imaging of oxide catalysts by using AFM

摘要

Atomic force microscopy (AFM) has become an important characterization tool of solid surfaces since its invention by Binning etal. In 1986. AFM, applicable to non-conductive solid surfaces under various environments, should be an ideal tool for elucidating catalytic microstruc- tures. Despite its potential, there are only a few successful imaging of practical catalysts because the imaging technique is by no means routine. A review was presented of the recent researches with aFM that were directed toward powdered oxide catalysts, clay and zeolite.
