Synthesization and Photocatalytic Activity Evaluation of Float-Type g-C3N4 Microtubes

Abstract

Float-type g-C3N4 microtubes were created by hydrothermal method and calcination using g-C3N4. Substances after hydrothermal synthesis and float-type g-C3N4 microtubes were investigated by XRD and SEM. The photocatalytic activity of float-type g-C3N4 microtubes was evaluated by methylene blue decomposition. According to these results, the substance, such as a needle, was found to have the same crystal structure as g-C3N4. In addition, it was confirmed that the needle-like substance was hollow inside, according to the SEM result. This substance can float on water. Therefore, Float type g-C3N4 microtubes can receive more light, and the decomposition rate has increased compared to g-C3N4.
