Preparation of nanometer FeCuP alloy and its application in decomposition of PH3

A new ternary Fe-based alloy catalyst FeCuP applied to decompose PH3 was prepared with low-cost material by chemical reduction deposition method. The properties of it were characterized by XRD, ICP and SEM. Its catalytic activity on the decomposition of PH3 and the decomposition conditions were studied. FeCuP alloy exhibits high thermal stabilities and high catalytic activity. Using it as catalyst, the decomposition temperature of phosphine decreases from over 800 degrees C to 400-500 degrees C. The decomposition rate of phosphine achieved 100%. (c) 2007 Chang Xiu Han. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
