Gold: A Relatively New Catalyst
Gold Catalyst
2009/7/29
Work performed with gold catalysts before about 1980 is briefly reviewed, and early indications of the importanceof using very small particles to obtain good activity are noted. The apparent contrast ...

Gold Novel Catalyst
2009/7/28
Gold can be deposited as nanoparticles on a variety of
support materials by coprecipitation or depositionprecipitation
of Au(OH)3, grafting of organo-gold

Decomposition of Fe5C2 catalyst particles in carbon nanofibers during TEM observation
carbon nanofiber HRTEM iron carbide
2010/1/18
The effect of an electron beam on nanoparticles of two Fe carbide catalysts inside a carbon nanofiber was investigated in a transmission electron microscope. Electron beam exposure does not result in ...
