Commonly avilable hydrogen peroxide contains a stabilizer as an
additive. This does not eliminate but slows down the decomposition of
H2O2. Peroxide with no additive is probably difficult to find because of
very short shelf life.
Peroxide decomposition is yet another redox reaction that is catalyzed
by presence of trace amount of transition metal impurities like iron,
manganese, copper, etc.
