Most of the polymer-supported noble metal catalysts had high optical catalytic activity.Furthermore

they were separated readily from products after reaction and could be reused several times without any remarkable loss in optical catalytic activity

which became an important researching issue.The general polymeric supports included organic polymers and inorganic-organic hybrid composites.According to the type of polymeric support

the syntheses and applications in the hydrogenation of alkylenes

dienes

alkynes and nitroaromatics

etc.

of polymer-supported noble metal catalysts as Pt

Pd and Rh were summarized in this paper.The research on dendrimer-supported catalyst

multiple-metal-loaded catalyst and nano-gold-loaded catalyst was also generalized and commented.
