Microwave assisted synthesis of reduced graphene oxide incorporated MOF-derived ZnO composites for photocatalytic application

Metal-organic frameworks (MOF) have been arousing a great interest due to their excellent properties. In this work, reduced graphene oxide (RGO) incorporated MOF-derived ZnO composites have been prepared via the microwave assisted method and used as photocatalysts for the photocatalytic degradation of methylene blue (MB). The results indicate that as-prepared composite with 1.5 wt.% RGO shows an optimal photocatlytic performance and the photocatalytic activity is 1.78 times of that using pure ZnO. The photocatalytic performance improvement can be attributed to RGO being able to enhance light absorption, separate the photogenerated electrons and suppression of charge carriers recombination.
