MOF derived hollow CuO/ZnO nanocages for the efficient and rapid degradation of fluoroquinolones under natural sunlight

Guanwen Su et al.

Summary: In this study, hollow ZnO nanocages were prepared by calcining ZIF-8 and CuO was synthesized in situ on the surface of nanocages, resulting in the synthesis of hollow CuO/ZnO nanocages as a novel photocatalyst. This is the first study to achieve position-controllable synthesis of CuO/ZnO heterojunction on the inner and outer surfaces of hollow nanocages. The experimental results showed that hollow CuO/ZnO nanocages exhibited superior photocatalytic performance and synergistic effect, and favored the separation of photogenerated carriers. A suitable photocatalytic degradation mechanism was proposed based on the results. These findings have important implications for the application of photocatalytic materials.

Photocatalytic properties of coating materials enriched with bentonite/ZnO/CuO nanocomposite

Olga Dlugosz et al.

Summary: The study showed that ZnO nanoparticles modified with specific metal oxides exhibit high photocatalytic activity, with the nanocomposite being effective in coating materials such as paint and plaster for dye removal. The efficiency of the hybrid systems was influenced by time and initial concentration, with the modified paint demonstrating the highest dye removal efficiency.
