The methods used to deposit a catalyst on structured surfaces are reviewed. Physical methods such as PVD and chemical methods (sol–gel, CVD, direct synthesis, etc.) are described. The coating of catalysts based on oxide, zeolite or carbon support is detailed on various surfaces such as silicon or steel microstructured reactors, cordierite monoliths or foams, fibres, tubes, etc.

Microreactor numbering-up in multi-scale networks for industrial-scale applications: Impact of flow maldistribution on the reactor performances

A methanol steam micro-reformer was constructed to produce hydrogen (H2) for polymer electrolyte membrane fuel cells (PEMFCs), in which a Cu/Zn/Al/Zr catalyst was supported on metal foams. To optimize the performance of the micro-reformer, the effect of metal foams on the catalytic property was investigated in details, including catalytic activity, carbon monoxide (CO) selectivity and mechanical properties. It was found that the strong interaction between the Ni or FeCrAl metal foams and catalyst resulted in the low activity for water gas shift (WGS) reaction, therefore, increased the CO selectivity significantly. As a general principle, it was proposed that the metal materials poisoning or reducing the reforming activity should be excluded in the design of micro-reformers.
