Green Synthesis and Characterization of Metal Oxide-Cellulose Nanocrystals (MO-CNC)

MO-CNCs were developed using rice straw, sugarcane bagasse, and corn straw as raw materials. The extracted CNCs were incorporated with different ratio of CuO and ZnO nanoparticles. Both nanosized spherical and rod-like structures of CNCs were obtained. Incorporation of MO nanoparticles produced the nanoparticle CNC matrix with prominent agglomeration. Bands were observed at around 400 to 600 cm-1 attributed to MO-CNC interaction. Incorporation of MO nanoparticles improved the thermal stability of CNC. The peak temperature obtained for the products were within the range of 308- 360 0C.
