Abstract
Flame spray synthesis is investigated as a method for one step
synthesis and deposition of porous catalysts onto surfaces and
into microreactors.
Using a standard photolithographic lift-off process, catalyst can
be deposited on flat surfaces in patterns with sub-millimeter
feature sizes. With shadow masks, porous catalyst layers can be
deposited selectively into microchannels.
Using Au/TiO$_2$ as test catalyst and CO-oxidation as test
reaction, it is found that the apparent activation energy of the
deposited catalyst is similar to what is normally seen for
supported gold catalysts in the literature. The surface area of
the deposited material is more than twice as large as when the
flame-produced material is collected on a filter at the outlet of
the flame reactor unit.
