| dc.description | Au nanoparticles were prepared in solution
using HAuCl4.3H2O as Au precursor, sodium citrate as
stabilizing agent and sodium borohydride as reducing
agent. The influence of synthesis parameters such as
BH4:Au and Citrate:Au ratios were studied. In a further
step, the stabilized Au nanoparticles were supported on
TiO2 with different Au loadings (wt%). The resulting Au/
TiO2 catalysts were characterized by Energy-dispersive
X-ray spectroscopy, X-ray diffraction and Transmission
Electron Microscopy and tested for the preferential
oxidation of carbon monoxide in hydrogen-rich stream.
Au nanoparticles stabilized in solution were obtained
with sizes in the range of 3-4 nm. After supported on TiO2,
the Au nanoparticles size did not change and the Au/TiO2
catalysts exhibited excellent performance and stability in
the temperature range of 20 - 50 ??C. | |
