A microcatalytic support realised by LIGA technique: the devil's comb

Microreactors are considered a new opportunity for R&D operations and for the production of hazardous or ultrapure materials where and when they are needed. Most chemical reactions are enhanced by a catalytic process involving a porous support for the catalyst. A microstructure exhibiting a fractal property is proposed as a porous network. A LIGA technique is used to manufacture a number of such structures. Limits and difficulties occurring are discussed.
