1. A method for the decomposition of hydrogen peroxide, the method comprising the steps of:
a) immersing an ion exchange resin in a manganate (II) solution;
b) performing ion exchange thereby transporting manganese from the manganate (II) solution to the immersed ion exchange resin, thereby forming an ion exchanged ion exchange resin;
c) drying the ion exchanged ion exchange resin;
d) heating the dried ion exchange resin to carbonize and activate the dried ion exchange resin, thereby forming an activated carbon catalyst;
e) immersing the activated carbon catalyst in hydrogen peroxide thereby decomposing the hydrogen peroxide into water and oxygen; and
f) recovering a remaining activated carbon catalyst.
