Photocatalysis is a promising technology to remove organic dyes. Among various photocatalysts, metal oxides have technological importance in environmental remediation and electronics because of their capability to generate charge carriers when stimulated with required amount of energy. The promising arrangement of electronic structure, desirable bandgap, and charge transport characteristics of metal oxides has made possible its application as photocatalyst. Recently, core-shell structure that the metal oxides are covered with metal-organic framework (MOF) shell has been immerging issue. These MO@MOF photocatalysts are known to show high catalytic performance by synergistic effect between MO and MOF. But some articles show reverse results, and more research should be needed. Herein, we synthesized ZnO@ZIF-8 and the morphology of ZIF-8 was rationally tuned. We found that ZIF-8 layer can improve photocatalytic activites of ZnO only at controlled morphology. |
