I prepared a metal/carbon network via a solid state reaction. I want to remove the carbon (amorphous graphite) and leave the pure metal network. However, the melting point of the metal is lower, and the nano-scale microstructure of the metal is easily to be destroyed via a thermal treatment. So I really hope there is the way to remove the carbon mildly (under room temperature is the best, lol ).
Well, it depends on how your metal network can resist oxidation. Carbon can be oxidised, but metal also. What is your metal ? I have seen in a paper amorphous carbon removal by treatment in H2O2 near room temperature, but I have not experienced it myself, so I am not sure it'll work in your case. And of course, depending on the nature of your metal, this way of doing can be inappropriate. Better checking the redox potential of your metal and compare it with the H2O2/H2O system, which also depends on the pH.
