I have three questions I can't find an answer for online about catalytic converters:

1. How does rhodium remove nitrogen from nitrogen oxides?

2. Why do catalytic converters need to be hot to operate at full efficiency?

3. Why are platinum and rhodium used? What properties do catalytic converter metals need to have?

I appreciate any answers, thanks!

research task, I don't need to go into this much detail I guess but I would like to understand the process in more detail.

No detail on my three questions on wikipedia, but I found an answer for my third question elsewhere, so any help with the others would be appreciated.
