Synthesis of catalytic fibers employing atmospheric pressure arc plasma technology

The principle of non-equilibrium atmospheric pressure arc plasma technology for deposition of high temperature catalytic fibers is considered. CuO and Cr₂O₃ supported catalytic fiber containing less than 2 μm filaments with excellent thermal and mechanical stability were prepared. A system with linear DC plasma torch cooling step-formed cooper anode was used. The data of this study show that the use of plasma deposition technology has significant consequence in the formation of high thermal resistant catalytic fiber which represents a new approach in the environmental protection area.
