Abstract: This note reports a successful preparation of a new catalyst particles through the reaction between Ni~(2+) and H_2PO_2~- in aqueoud solution at room temperature. X-ray diffraction pattern indicates that the particles are in amorphous and alloying state. Transmission electron micrograph shows that the particles are spherical and the size distribution is very narrow. The average diameter of the particles is determined to be about 100 nm which is in“ultrafine”scale.

Key words: Amorphous, Ultrafine particle catalyst, Narrow size distribution
