Abstract: The C3N4-decorated ZnO and Ag/ZnO nanoparticles were prepared using melamine and ZIF-8 as precursors after thermal treatment under air condition. The results from the structural analysis suggested that the presence of the metallic Ag as well as C3N4 in the composite and the introduction of the melamine could slightly enhance the aggregation of the particles of the three dimensional structure of ZnO and Ag/ZnO. However, the presence of C3N4 and Ag could boost the utilization of the light and increase the separation of electrons and holes. Finally, the photocatalytic degradation of methyl orange indicated that the C3N4-decorated ZnO and Ag/ZnO displayed an enhanced ability in comparison with pure ZnO and C3N4, which suggested that the synergistic effect of Ag and C3N4 played an important role in the catalytic process.
