“…Recently, many researchers shift the attentions towards heterogeneous catalysis topics with use of MMT-based composites [11,12,13,14]. In particular, MMT/polymer composites have been recognized as good supporting materials for immobilization of transition metal catalysts applied in organic reactions [15,16,17,18,19,20,21]. With synergetic processes of ion-exchange with interlayer cations of MMT and complexation with polar polymers, the transition metal cations, like Pd 2+ will be easily immobilized on MMT/polymer supports.…”
