Ammonia oxidation in a microreactor

How do you add the catalyst?

The ammonia oxidation reaction involves the use of a heterogeneous rhodium-platinum catalyst. How this catalyst is 'charged' to a microreactor is definitely important in terms of how well the reactor performs. The walls of the microreactor trench need to be loaded with active catalytic sites. One method for obtaining this type of surface is to use anodic oxidation to generate walls with pores that can be used to contain (and immobilize) the catalyst. The anodic oxidation process can be finely controlled to produce pores with a uniform, known size and depth, at a uniform, known density. After the walls have been treated, catalyst is added.
