Abstract
Transparent monolithic aerogels based on silica, the bioderived polymer chitosan, and coordinated ions are employed to serve as a three-dimensional scaffold decorated with metal ions such as Au, Pt and Pd ions. It has also been found that the metal aerogels, such as Au(III) aerogels, can be imaged photolytically to produce nanoparticles.
