“…It has been indicated that there are macromolecular effects in catalytic systems because the polymer ligands modify the electronic structure of the center metal to yield higher activity and higher selectivity for catalytic reactions than that of their smaller molecule complex analogs 1. An interesting phenomenon reported in previous studies is that the polymer‐metal complex catalysts have always been activated by hydrogen before being used for either hydrogenation or oxidation 2–4. We now consider that the activation process is a complex transformation process of coordinated metal ions to the nanosized metal cluster.…”

A series of nanosized palladium catalysts supported by silica and polymers, prepared by the complex transformation method, were used for catalytic hydrogenation of nitrobenzene. It was found that both the thickness of the polymer layer and the size of the palladium particles would affect the catalysis. The results indicated that the reaction rate would be optimal when a polymer supporter formed a single layer on the silica surface. The catalytic activity of the catalyst would not simply increase with the decrease of the size of palladium particles. The effects of other conditions on the catalytic properties, such as the order during preparation of the catalyst, solvent, and the pH values, were also discussed.

“…Hirai et al showed that alcohols could serve as reducing agents, 5 and that in the presence of a polymeric stabilizer Pd NPs could be prepared. 6 Using a similar strategy, poly(2-vinylpyridine) (P2VP) in the form of linear homopolymers, [7][8][9][10] block copolymers, [11][12][13] and nanospheres 14 was shown to complex with palladium species, even at high temperatures and pressures, 15 and to lead to the formation of Pd NPs aer reduction of the metallic species.…”
