Rhodium honeycomb catalyst microstructure

Figure 1.5 Rhodium honeycomb catalyst microstructure device. The microchannels have been manufactured by wire erosion.

Figure 2.5 Honeycomb catalyst made of microstructured rhodium foils. The single foils (left) have been machined by wire spark erosion and then bonded to form the honeycomb (center, right SEM).
