ZnO@C纳米复合材料的制备及其光催化活性增强的研究

ZnO@C nanocomposite was synthesized by mixed calcination method using glucose solution as the carbon precursor solution, the morphological and structural properties were characterized by transmission electron microscope, and the photocatalytic degradation properties were measured by UV-Vis diffuse reflectance spectra. Compared to the obtained samples, ZnO@C (0.25 M) displayed the highest efficiency for the photocatalytic degradation of rhodamine B (RhB) under ultraviolet light irradiation (λ=254 nm), increased by nearly 33% to pure ZnO-nanoparticals. This result indicated that mixed calcination method could be employed to implement the nano-composite of carbon and ZnO-nanoparticals, the increased photocatalytic activities revealed that introduce of carbon to metal nanoparticles opens possibilities to provide some new insight into the design of highly active photocatalyst for environmental governance applications.
