Micro-reactors catalyst coating techniques

For this micro reactor version, the catalyst was coated on the AlMg3 platelet as a thin silver layer by sputtering [43,44], A further set of platelets was covered with an a-alumina layer by sol-gel technique and impregnated by a three-step procedure with silver lactate. 

Coating on micro structures is still dominated by manual coating techniques. For future automated production of catalysts and even complete reactors, automated coating procedures will become crucial. Some new approaches in coating technology especially suited for micro structures are described in Section 4.12.4, Online Reactor Manufacturing.
