Abstract

It is shown by the use of digital image processing techniques in electron microscopy that the shape of small rhodium particles supported on titania depends on the hydrogen reduction temperature. In sample I (1 wt%) reduced at 473 K, one-dimensional rows and two-dimensional irregular arrays of rhodium were observed. In sample II (3 wt%) reduced at 573 K, three-dimensional rhodium particles about 2 nm in size were observed. In addition, an apparent support reduction around the particles was revealed.
