AI Thread Summary
Rhodium removes nitrogen from nitrogen oxides through a reduction reaction, converting harmful NOx gases into nitrogen and oxygen. Catalytic converters need to reach high temperatures to facilitate these chemical reactions, as the catalysts become more effective at elevated temperatures, enhancing the conversion efficiency of pollutants. Platinum and rhodium are used in catalytic converters due to their excellent catalytic properties, including high resistance to poisoning, ability to withstand high temperatures, and effectiveness in promoting oxidation and reduction reactions. For further detailed insights, additional resources like academic papers can provide comprehensive explanations of these processes.

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!

Is it your homework?
 
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.
 
Start with wiki, plenty of information there.
 
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.
 
Thanks a bunch, that's a great source, answered both my questions!
