摘要

Removal of PH3 from industrial gases have attracted extensive attention due to its high toxicity and catalyst poisoning characteristics. In this study, a series of copper-based support-free catalysts were synthesized by a facile method using different nitrogen and carbon sources. The 100% removal of PH3 could reach 540 min in micro-oxygen environment by using the obtained catalyst. The X-ray diffractometer (XRD) and X-ray photoelectron spectroscopy (XPS) results exhibited that the formation of Cu3P was contributed to the deactivation of the catalysts, which was considered as active component for the decomposition of PH3. The PH3 decomposition performance could achieve 99% under 450 ℃ with 90% yield of H2 using the exhausted catalysts. This strategy is beneficial for the development of dephosphorization catalyst and provides a new route for the secondary use of exhausted catalysts.

Graphical Abstract

A facile strategy was employed for synthesize support-free catalysts for PH3 oxidation by using Cu(NO3)2 and different nitrogen resources or carbon resource. The performance were thoroughly compared. The exhausted catalyst was conducted in the PH3 catalytic dissociation reaction, where the conversion rate of PH3 could reach 99% with 90% hydrogen production under 450 ℃.
