N2 - 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.
