Can an internal combustion engine run on hydrogen peroxide?

Yes in theory , You could run an IC engine on hydrogen Peroxide ( HP). This would run more like a diesel engine than a gasoline engine. HP would require a Platinum or Palladium Catalyst in the cylinder head to make it combust this is the only way you can get it to burn. HP is not combustible ,but is a great oxidizer in a rocket engine. The only why to use it as a fuel is to use a catalyst to break the chemical bonds. I feel you would have better luck trying to make a Rotary engine run on HP rather than a piston engine. I suspect it was used on U-boats as an oxidizer in addition to diesel fuel, much like the Russians used liquid oxygen. This adaptation will let you run your main engines while diving under the water. I believe a lot of torpedo's use this principal as well.
