- 06:54Results: Morphologies of the MHM-TOCN, MHM-TOCN/SBR, MHM-TOCN/TiO2, and MHM-TOCN/SOCF
- 08:39Conclusion
Here, we present a general protocol to prepare a variety of microhoneycomb monoliths (MHMs) in which fluid can pass through with an extremely low pressure drop. MHMs obtained are expected to be used as filters, catalyst supports, flow-type electrodes, sensors and scaffolds for biomaterials.
