Synthesis and Catalytic Degradation of PEF, ENR, and CIP by g-CN/TCNQ/Eu Composite.

By using melamine as a precursor for the copolymerization process, g-CN and g-CN/TCNQ/Eu complexes with various amounts of doping were created. These complexes were then examined using XRD, FT-IR, SEM, TEM, XPS, PL, UV-vis, and I-T. The degradation rates of pefloxacin (PEF), enrofloxacin (ENR), and ciprofloxacin (CIP) were 91.

Analysis of Photocatalytic Properties of NS-CQDs/g-CN Composites.

N- and S-doped CQDs were prepared using L-cysteine as a precursor. Different NS-CQDs/g-CN composite photocatalysts were formed by modifying graphite-phase carbon nitride with different contents of NS-CQDs using a hydrothermal method. The morphology, constituent elements and functional groups of the composite photocatalysts were analyzed by SEM, EDS, TEM, Mapping, XRD and FT-IR as a proof of its successful preparation.
