The relationship between the adsorption-reduction capacity of Pt(IV) a
nd the preparation conditions, the surface area of ACF, as well as the
effect of the reaction conditions such as the ratio of solid to liqui
d, the concentration of Pt(IV), reaction temperature and solution pH w
ere studied. The dispersion and structure of the platinum produced wer
e investigated by use of SEM and XRD. (C) 1997 Elsevier Science Ltd.
