Mechanical compaction of melamine controls carbon nitride structure and enhances AO7 photodegradation (opens in new tab)

Graphitic carbon nitride (g-C3N4) is a promising metal-free photocatalyst; however, its performance strongly depends on the synthesis pathway and resulting structure. In this study, a simple compaction-assisted method for the preparation of melamine-derived carbon nitride materials in air is proposed. Mechanical compaction of the melamine precursor before thermal treatment enables improved packing density and more homogeneous heat transfer, leading to controlled structural evolution during po...
