Chitosan as efficient porous support for dispersion of highly active gold nanoparticles: design of hybrid catalyst for carbon-carbon bond formation.
Macroporous catalyst was obtained by dispersing nanosized gold in the fibrils of the chitosan matrix, followed by CO(2) supercritical drying of the resulting hybrid material. The accessible gold nanoparticles are highly active for carbon-carbon cross coupling reactions.
