In this study, a new method of dissolving g-C3N3 in concentrated sulfuric acid and its solution stability at low temperature were investigated. The findings provide possibilities for the application of g-C3N3 in fields such as photocatalysis, electrochemistry, and energy storage.
As a new type of carbon nitride material with high nitrogen content, g-C3N3 has promising application potential in the fields of photocatalysis, electrochemistry and energy storage. In this study, we found that g-C3N3 can be dissolved in concentrated sulfuric acid at room temperature to form a true thermodynamic solution for the first time, and the g-C3N3 can be reversibly precipitated successfully by adding deionized water to the solution. The solution with a high concentration of 300 mg ml(-1) exhibits good stability even at -40 degrees C. The dissolution phenomenon of g-C3N3 in concentrated sulfuric acid and the solution stability at low temperature will pave the way for its potential applications.
