摘要：

Zeolitic imidazolate framework-8 (ZIF-8) derived ZnO and ZnO@Ta2O5 (Ta2O5 anchored to ZIF-8 derived ZnO) nano composites were synthesized by a rapid microwave synthesis method. The synthesized ZIF-8, ZnO, and ZnO@Ta2O5 were further characterized by XRD, XPS, BET, SEM, and HR-TEM. XRD refinement data confirmed the formation of a pure and single hexagonal wurtzite structure in ZnO and ZnO@Ta2O5. The ZnO@Ta2O5 nanocomposite was used as a working electrode in methanol oxidation reaction (MOR) and urea oxidation reaction (UOR) in alkaline media. The activity and stability of the ZnO@Ta2O5 electrode was compared with those of ZIF-8 and ZIF-8 derived ZnO. As per our results, the ZnO@Ta2O5 electrode exhibited promising activity and stability in these reactions.
