Ion-exchange Resins and Polypeptide Supported Catalysts: A Critical Review


Kinkar Biswas*, Sujit Ghosh and Basudeb Basu*   Pages 1 - 13 ( 13 )


The Green chemistry promotes environmentally benign protocols comprising of energy consumption, atom efficiency and sustainability of chemical processes. Over the last three decades, scientists have concentrated on the exploration of new methods to replace toxic and harmful solvents by more environmentally benign alternatives. Additionally, the design of more environmentally important and low impact protocols including the use of magnetically separable nanomaterials, solvent-free reactions, ultrasound-assisted reactions and microwave-assisted organic synthesis (MAOS) are also considered as greener protocols. Again, catalysis is considered as a foundational stone of green chemistry. Conventionally, the homogeneous catalysts are frequently applied in classical organic reactions to achieve target molecules. Suitably designed heterogeneous catalysts offer several advantages over homogeneous counterparts including easy separation and recyclability. Several polymeric materials and composites have been applied as heterogeneous catalysts.
