Float-type carbon nitride microtubes (C3N4MT) were synthesized by a calcined hydrothermal process of melamine. Float-type C3N4MT was evaluated by SEM, TEM, and XRD. The XRD showed that float-type C3N4MT was similar to graphitic carbon nitride (g-C3N4) created by calcining melamine. The SEM images revealed that float-type C3N4MT had a variety of tube structures of various sizes. In addition, the TEM images showed that the surface of float-type C3N4MT was covered with a porous structure. Because of its tubular and porous structure, its density was lighter; consequently, it could float on water. Float-type C3N4MT was placed in a liquid microbial growth medium (LB medium) mixed with soil bacteria inoculum to investigate its photocatalytic antibacterial performance on soil bacteria. Float-type C3N4MT was found to reduce the growth of soil bacteria by 15%. Also, float-type C3N4MT can receive more sunlight energy by floating on the water’s surface, giving it an advantage in antibacterial activity in muddy water. Therefore, the synthesized float-type C3N4MT can be used for environmental antibacterial applications.
