Js. Moon et al., The reduction reaction of dissolved oxygen in water by hydrazine over platinum catalyst supported on activated carbon fiber, APP CATAL A, 184(1), 1999, pp. 41-48
The reduction reaction of dissolved oxygen (DO) by hydrazine was investigat
ed on activated carbon fiber (ACF) and Pt/ACF catalysts using a batch react
or with an external circulating loop. The ACF itself showed catalytic activ
ity and this was further improved by supporting platinum on the ACF. While
the reaction order of DO was obtained as 0.5 on both the ACF catalyst and t
he Pt/ACF catalyst, that of hydrazine was observed to be 1.0 on the ACF cat
alyst and 0.25 on the Pt/ACF catalyst. The catalytic role of platinum is as
cribed to its acceleration of hydrazine decomposition, based on electric po
tential and current measurements, as well as the kinetic study. The activat
ion of oxygen may to be attributed either to ACF or platinum. (C) 1999 Else
