Activation of Carbon Nitride Solids by Protonation: Morphology Changes, Enhanced Ionic Conductivity, and Photoconduction Experiments.

The article reports that carbon nitrides can be reversibly protonated by strong acids, modifying dispersibility or solubility, electronic structure and surface area. Preparation of new series of g-C,3N 4 based functional hybrid materials via counteranion exchange. The study shows that the high surface area could be preserved after recovery by heating and enables improved sintering which allowed direct measurement of its photoconductivity.
