Palladium hollow spheres

An interesting approach has been introduced with uniform palladium hollow spheres, produced from the palladium complexes immobilized on mercaptopropyl-derived silica spheres. The silica template is then removed by treating with HF to produce hollow palladium spheres. Thus obtained palladium has shown very high efficiency... [Pg.180]

Interestingly, the MC approach for this reaction has been also developed using heterogeneous catalysts such as KjCoWjjO j-SH O [100], supported heteropoly acids [101], montmorillonite [102], sulfuric acid-modified PEG-6000 [103], or organometallic hollow spheres bearing bis(Ai-heterocyclic carbene)-palladium species [104], among others. [Pg.351]

Fig. 17 Bottom Pd/X9 clusters used to study the adsorption of a Pd atom (dark sphere) on several metal surfaces. Cluster 1 models the bonding of Pd to an fee hollow site of Al(lll), Rh(lll) or Pd(lll). Cluster II models the adsorption of palladium on a hollow site of W(110). Top calculated 4d electron population for the palladium adatom in the Pd/X9 clusters. Reprinted from ref [32].
