I'll give you the General Idea behind it.
You put a known amount of hydrogen peroxide in a test tube that is connected to a gas syringe and burn the test tube/allow the powder inside it to decompose ... for certain time intervals ex every 1 minute record the time and the volume of gas collected
the one the gave out the most gas in the same period of time is the best catalyst.
I hope I helped
