The immobilization of homogeneous catalysts on supports is used
to facilitate the catalyst separation from reaction mixtures and their recycling.
In addition to this practical merit, some reports have demonstrated that the
immobilization of a catalyst can also positively influence catalytic
performance (increase in catalytic activity, stability and selectivity). In this
chapter, the positive effects of immobilization on catalytic efficiency are
discussed in terms of site-isolation, steric constraints, cooperation effect and
imprinting effects, etc., with the aim to understand as to how such effects lead
to positive changes in catalytic properties.
