Original Abstract
This study focuses on the development and characterization of visible-light-activated photocatalytic coatings based on graphitic carbon nitride (g-C₃N₄) with an integrated porous structure. The porosity was achieved using camphor as a porogenic agent, which was removed from the structure through sublimation. The resulting thin films were applied to substrates using various techniques. Analytical methods such as SEM, XPS, FTIR, and UV-VIS confirmed their structural and chemical integrity. Subsequently, the efficiency of a selected porous sample was compared to that of a compact one in the degradation of tetracycline in a photomicroreactor. The results demonstrate that improved photon accessibility to the active surface of coatings with macroporous morphology leads to an increased oxidation rate, representing a significant contribution to the treatment of water contaminated with pharmaceuticals.
