Abstract

Metal nanoparticles (Au, Ag, or Pd) functionalized with hydroxy-terminated alkane thiols can be dispersed in sol-gel mixtures to give alcogels and, after supercritical drying, aerogels containing up to 90 wt% of nanoparticles. Layered or patterned nanoparticle/aerogel monoliths can be prepared by sequential casting or molding of the sol-gels.
