要旨

For catalyst construction, biopolymeric chitosan has attracted the interest of many researchers due to its biodegradability and economic viability. Accordingly, this study utilized chitosan as a green support to produce a versatile heterogeneous catalytic system. Chitosan was first functionalized with indigo carmine (IC) and then metal nanoparticles (i.e., Cu2O and CuO) were immobilized on the IC-functionalized chitosan (IC-CS). The successful synthesis process was fully confirmed using different techniques such as SEM, FT-IR, EDX, XRD, TGA, and DTG. After ensuring catalyst fabrication, the catalytic activities of Cu2O/IC-CS and CuO/IC-CS were investigated for the oxidation state of copper in the click reaction and CO2 fixation, respectively. The obtained results revealed the application of these biocatalysts in the above-mentioned reactions with water as a green solvent in the shortest time with high efficiency and selectivity for the desired products.
