Fabrication of microtubular reactors coated with thin catalytic layer (M=Pd, Pd−Cu, Pt, Rh, Au)

Novel micro tubular reactors composed of Inconel 625 support, TiO2/Ti intermediate layer and thin catalytic metal film (Pd, Pd−Cu alloy, Pt, Rh, and Au) were fabricated by continuous electroless plating technique. The reactors withstood high temperature (400 °C) and high pressure (30 MPa) water flow without loss of catalytic metals. The high catalytic efficiency of the reactors was demonstrated by the rapid and complete decomposition of organic dye in the flow system.
