Catalyst for microelectromechanical systems microreactors

A microreactor apparatus, comprising:

• a silicon wafer that forms a silicon microreactor body,
• a silicon microchannel array in said silicon microreactor body,
• a multiplicity of channels in said silicon microchannel array in said silicon microreactor body, wherein said multiplicity of channels each have a pressure drop,
• an inlet in said silicon microractor body, said inlet connected to said channels,
• an outlet in said microractor body, said outlet connected to said channels,
• said inlet, said outlet, and said channels arranged in a symmetrical layout resulting in said pressure drop in each of said channels being an equivalent pressure drop,
• a substrate over said microchannels, and
• a catalyst coating said channels wherein said catalyst coating said microchannels comprises a nanostructured material that is composed of 10 to 50 Å spherical subunits.
