I was looking up oxidizers in two aspects, economy and power. Since much of math goes over my head, I got almost nothing.

What would be most economical and most powerful potent oxidizer choice available today? Is there a catalyst which can be helpful here?


Oxygen is the best oxidiser that's also simple to handle and inexpensive. Better oxidisers exist, but they are expensive and can be toxic and/or corrosive, making them difficult to handle. In particular, fluorine can give very high specific impulse, but is nearly impossible to work with safely so it's never been used in production rockets.

Here's a good list of propellants and oxidizers.
