Preparation of Au–Pd bimetallic nanoparticles in porous germania nanospheres: A study of their morphology and catalytic activity

Size controlled Au–Pd bimetallic nanoparticles with an average size of 7–10 nm were grown in porous germania nanospheres. The properties of the resulting nanocomposites were characterized by electron microscopy, energy dispersive spectroscopy, and ultraviolet–visible spectroscopy. The catalytic acti...

Zusammenfassung:Size controlled Au–Pd bimetallic nanoparticles with an average size of 7–10 nm were grown in porous germania nanospheres. The properties of the resulting nanocomposites were characterized by electron microscopy, energy dispersive spectroscopy, and ultraviolet–visible spectroscopy. The catalytic activity of the nanocomposites was also examined by studying the degradation of p-nitroaniline.
