Abstract

Metal oxides are commonly used as the supports of gold nanoparticles for catalytic CO oxidation, whereas metal salts are rarely considered suitable supports. In the present work, we developed a new kind of gold nanocatalyst supported on heterostructured PbSO₄-MCF mesoporous materials that was prepared by an in situ growth method using dodecylbenzenesulfonate (SDBS) as a sulfonate precursor. It was found that an Au/PbSO₄-MCF (SDBS) catalyst preheated at 300 C showed high CO conversion below 100 C. In addition, the stability of selected catalysts was studied as a function of time on stream. Because of the alteration of surface properties, these Au nanocatalysts were highly sinter-resistant.
