Abstract:
Nanomaterials have excellent anomalous, abnormal electrical, optical, mechanical and catalytic properties,
opening up new research and application fields for the research of new materials. Zinc oxide has the advantages of low cost,
non-toxic and harmless, large band gap width and high electronic excitation energy, and has been widely used in the
development of functional devices. However, ZnO has some defects, such as oxygen vacancies （ Vo ) and zinc deficiency
（Zni ), rapid recombination rate of photoelectron-hole pairs and low adsorption properties. Doping can change the structure
of the material and improve its performance. Graphene is a two-dimensional planar structure material with a thickness of
