Hello,

I am working on ideas to create an educational video about the chemistry of copper and nitrogen oxides. The goal is to used copper ii nitrate to form nitrogen dioxide for production of nitric acid. On my initial searching I found that copper ii nitrate may be heated to around 180 C to liberate the NO2. I was wondering if there was any way to have the gas be released at a lower temperature. Are there any catalysts or methods of reducing the temperature of this reaction? Thanks in advance for any *delete me*

More easy to dissolve, copper, lead, etc. Into nitric acid.
Bewahren nitrous gas is very toxic.

You may have already found this link but if not it might be of interest to you. I've done this demo many times with my students and it always provokes a good discussion about what's happening: https://edu.rsc.org/exhibition-chemistry/dissolving-copper-in-nitric-acid/2020047.article
