The development of multifunctional nanomaterials with diverse functionalities is a rapidly growing field with the potential to revolutionize numerous scientific and technological areas. This work describes the design, synthesis, and characterization of novel nanomaterials, as well as the application of these materials into the degradation of the tetracycline antibiotic under solar-like irradiation,1 hydrogen production2 and fluorescence sensing of metal ions like Ag+, AuCl4-, Fe3+ and Cr(VI).3 In addition to the aforementioned applications, the groundwork will be laid for the future exploration of these multifunctional nanomaterials in the fields of biomedicine and optics. The nanomaterials have been prepared by simple synthesis methods such as soft chemistry, microwave-assisted processes, and electrophoretic deposition. Figure 1 shows some of the synthesized multifunctional nanomaterials, including graphitic carbon nitride, some semiconductor materials, silver nanoparticles, LDHs and calcium carbonate.
