Effects of Different Types of γ-Al2O3 on the Activity of ...

Catalytic properties of Au nanoparticles supported on a one-dimensional γ-Al2O3(1-D) nanofiber and commercial γ-Al2O3 have been investigated during CO oxidation at low temperatures (298∼373 K). The kinetic data showed that the activity of Au catalysts could be remarkably improved by using γ-Al2O3 nanofibers as support compared to the commercial γ-Al2O3.
