摘要: 采用沉积-沉淀法制备了均一负载于碳纳米管(CNTs)载体的金属Ni和NiO,将其应用于PH3催化分解反应.通过XRD、TEM、XPS、BET等一系列检测手段,对样品的相结构、形貌、组分和比表面积进行了表征.研究结果表明,反应过程中,Ni和NiO很快被磷化为高活性的金属磷化物NiP2,作为反应的活性相.在420℃温度下,两样品对PH3的催化分解率均可达到99.5%以上.将反应中原位生成的NiP2进行催化反应,较钝化-还原的处理方式更有利于样品催化性能的保持.

Abstract: Metal Ni and NiO supported homogenously on carbon nanotubes samples were synthesized through deposition-precipitation method. The phase structure, morphology, composition and specific surface area of the catalysts were characterized by XRD, TEM, XPS, BET, etc., and the catalytic activity of the obtained catalysts were evaluated in the decomposition of highly toxic PH3 gas. The results indicate that during PH3 decomposition reaction, some of phosphorus atoms migrate onto Ni and NiO particles, and form metal phosphide-NiP2 which has high activity and acts as active phase in PH3 decomposition reaction. When operated in a fixed-bed reactor at 420℃, single-pass PH3 conversion of above 99.5% was achieved on both Ni/CNTs and NiO/CNTs samples. Furthermore, the method of in situ use of NiP2 generated in the initial stage of PH3 decomposition reaction gives much more catalytic activity than the NiP2 passivation-reduction method.
