Gold
nanopariticles is safety, environmental protection, non-toxic tasteless,
reliable performance, stable and easy to spread which apply to the biological
coloration, biocatalysis.
As catalyst Gold Nanoparticles can be supported on a variety of carriers, such as TIO2(Au/TiO2), SIO2(Au/SiO2), FE2O3(Au/Fe2O3), FE3O4(Au/Fe3O4), ZRO2(Au/ZrO2), AL2O3(Au/Al2O3) and carbon nanotubes.
