经过四氯金酸盐(HAuCl 4 )的典型还原后，可以方便地制备出Au/表面活性剂摩尔比高达0.06的稳定的Au纳米粒子-季铵表面活性剂水溶液。该溶液直接用于合成含有金纳米粒子的介孔铝硅酸盐。煅烧后的含Au纳米粒子的介孔硅铝酸盐具有高比表面积、大孔径、孔体积、高分散性的Au纳米粒子的优点，在80℃下表现出了CO氧化的催化活性。
A stable Au nanoparticles-quaternary ammonium surfactant aqueous solution with the Au/surfactant molar ration up to 0.06 has been conveniently prepared after a typical reduction of tetrachloroaurate salt (HAuCl 4). That solution was used directly to synthesize the mesoporous aluminosilicates containing Au-nanoparticles. The calcined mesoporous aluminosilicates containing Au-nanoparticles with the advantages of high surface, large pore size, pore volume high dispersity of Au nanoparticles, demonstrated the catalytic activity of the CO oxidation at 80 C.
