Abstract: Borax promotes cobalt(II) acetate catalysed decomposition of hydrogen peroxide. The rate constants are of the order 0.155-2.17x 10-3min-1  at 29°C. A cobalt borate catalyst, prepared by anion exchange reaction of cobalt(II) acetate with borax, can independently decompose hydrogen peroxide. Th"iscatalyst along with borax, decomposes hydrogen peroxide with a first order rate constant of 0.86x 10-3 min-1 at 29°C. The rate of decomposition of hydrogen peroxide in the presence of cobalt borate catalyst increases on addition of supporting substrates such as alumina and silica. However, triphenylphosphine decreases the rate of cobalt catalysed decomposition of hydrogen peroxide.
