近期我们报道了Au/FeOx-羟基磷灰石(HAP,Ca10(PO4)6(OH)2)催化剂应用于CO氧化反应的研究结果,该催化剂不仅具有很高的低温CO氧化活性和反应稳定性,同时也具有很好的高温抗烧结性能,即使600 ℃焙烧后依然能够维持很好的CO氧化反应活性.为了进一步研究Au/FeOx-HAP催化CO氧化反应中HAP和FeOx的作用,本文对该催化剂进行了更加深入的表征.X射线光电子能谱结果表明,HAP能与Au和FeOx形成强相互作用,进而在高温条件下稳定Au和Feq纳米粒子.根据原位漫反射红外结果,Feq则主要通过改变反应路径和中间产物的方式起到促进催化剂CO氧化活性的作用.结合透射电镜,穆斯堡尔谱和原位漫反射红外结果可知,Au/FeOx-HAP催化剂良好的反应稳定性源于其优异的抗碳酸盐累积能力.
