In the present study, manganese modified zeolitic imidazolate framework-8 (Mn-ZIF-8) and zinc-manganese bimetallic oxides (denoted as Mn@Zn), which was formed by Mn-ZIF-8 heat treatment, had been prepared and applied as photocatalysts to decompose methylene blue (MB) under UV radiation. The influence of manganese content on the structure of ZIF-8, as well as the temperature and heat treatment time of Mn-ZIF-8 material to produce Mn@Zn with high photocatalytic activity was investigated. Results showed that all Mn-ZIF-8 samples have photocatalytic activity, but the MB decomposition efficiency of Mn-ZIF-8 samples were lower than pure ZIF-8. The suitable condition for heat treatment of Mn-ZIF-8 to produce Mn@Zn with high photocatalytic activity was at 500 ºC for 5 hours. However, the MB decomposition efficiency of this sample only reached 22% after 180 minutes of UV radiation.
