Three-dimensional g-C3N4 aggregates of hollow bubbles with high photocatalytic degradation of tetracycline

Dicyandiamide would transform into the supramolecular MCA-like precursor through hydrothermal process and then transform into an intermediate with laminated sheets by hydrothermally treated in presence of P123, and the intermediate would first change to long balloons and then to hollow bubbles during the thermal polymerization.181
