Bimetallic AuPd nanoparticles on alumina supports were prepared using Au25(SR)18 precursors activated by mild calcination or LiBH4 treatment, followed by selective deposition of Pd via ascorbic acid reduction. Comparison of their catalytic activity for the oxidation of crotyl alcohol showed that bimetallic structure had significantly improved catalysis compared to Pd/Al2O3. In particular, AuPd samples...
Mesoporous TiO 2 nanostructures of spindle shape (diameter ∼6nm and length of 30nm) have been obtained at room temperature by a simple microemulsion method. The nanospindles are highly monodisperse with high surface area and high degree of thermostability. These TiO 2 nanostructures have a high surface area (∼200m 2 /g) and show nearly twice the photocatalytic efficiency than...
