How to add a reaction on the wall surface
 
How can I add a decomposed reaction on the wall surface coated by the catalyst? Thanks in advance.

Define the wall surface as a boundary separately from other walls. Depending on what the reaction at the wall surface, you may need to write UDF file and input at that wall surface.
