Cellulose has characteristic properties such as hydrophilicity, chirality, biodegradability and high functionality. A great deal of attention has been directed in recent years at cellulose and its derivatives focusing on their biological, chemical as well as mechanical properties. Cellulose and its derivatives can be used as supports since they are renewable, biodegradable and non-toxic.
Chitosan has shown good catalytic activity in organic synthesis without any post-modification. However, chitosan has been modified in most of the research by chemical modifications to serve the desired useful purpose. This biopolymer is interesting for catalytic applications due to low cost, hydrophilicity, chemical or physical modifications susceptibility for obtaining a special property, stability, nontoxic and biodegradable nature and having metal-anchoring functional groups.
With the increasing importance of greener, cleaner and more sustainable chemistry, a growth in applications has been observed for biomaterials such as cellulose and chitosan instead of petrochemical-based feed stocks in recent years [1-5]. Herein, various modifications on cellulose and chitosan was performed to obtain new catalytic systems applicable in the oxidation and reduction reactions.
