Abstract

The catalytic effect of Dy2O3 on the isothermal decomposition of sodium bromate has been investigated at 613.0 K. The data are analyzed in the light of various topochemical models. Dy2O3, being a p-type semiconductor, accelerates the decomposition of bromate by favoring the electron transfer reaction involved in the process. The plausible mechanism of the catalytic activity on the decomposition process is discussed.
