摘要： Ordered mesoporous Au was prepared using double-gyroid (cubic Ia3d) mesoporous silica KIT-6 as a template. The Au frameworks were formed within the template via a seed-mediated growth process. Au nanoparticles were initially prepared as seeds within the mesopores, and subsequently, they were grown under mild and controlled reducing conditions. The transmission electron micrographs and scanning electron micrographs of mesoporous Au after the removal of the template revealed the formation of mesoporous Au replicas. The small-angle X-ray scattering pattern of mesoporous Au reveals that the obtained mesoporous Au has a cubic I4132 mesostructure, which is different from that of the original template, implying that Au was deposited within only one mesochannel of the two interconnected ones. The seed-mediated growth process is a key factor in the successful formation of ordered mesoporous Au using a mesoporous silica template. Our preparative method can serve as a guide for further development of synthetic and materials chemistry of mesoporous Au.
