Preparation and application of supported amorphous alloy catalyst CoP/TiO₂

Abstract

A new supported amorphous catalyst CoP/TiO₂ was prepared by chemical reduction and characterized by ICP, XRD, TEM, BET and DSC. Its application in decomposing PH₃ to high purity phosphor and its catalytic activity were studied. The decomposition rate is over 95% at 450 °C. For comparison, unsupported CoP amorphous catalyst was prepared by the same method. The result suggests that CoP/TiO₂ exhibits higher thermal stability and catalytic activity than CoP, which is attributed to the high dispersion of CoP alloy particles on the support-TiO₂.

Keywords
