Research Project – Emiel Hensen/Lingqian Meng
The oxidation of methane to methanol and benzene to phenol are often included into the top 10 most difficult challenges of modern chemistry. The system in which Fe-ZSM-5 zeolites as catalyst and N2O as oxidant can easily perform this reaction in one step. While MFI nanosheets can exhibited excellent thermal stability, hydrothermal stability and strong acidity. Most importantly, the reduced crystal thickness facilitates diffusion and thereby dramatically suppresses catalyst deactivation through coke deposition. Besides, if H2O2 is chosen for the oxidant, the only product is H2O which is environmental benign. Instead of being added externally, it can also be produced in situ and immediately used for oxidation. In fact this method is considered as one ofthe most promising ways for performing demanding oxidation reactions.
Main goals of the project are:
- To dope ion on different thickness of nanosheets to synthesize Fe-ZSM-5 nanosheets.
- To try H2O2 as the oxidant in oxidation of methane to methanol with Fe-ZSM-5 nanosheets as catalysts, with or without copper in it.
- To explore an efficient Au/Pb/ZSM-5 nanosheet for the synthesis of H2O2 from H2 and O2
- To synthesize Au/Pd /[Cu,Fe]MFI nanosheet catalyst to get a catalytic circle.
