Synthesis of Metal Oxide Nanocomposites

Example 1

Preparation of AgNPs@CMC, FeNPs@CMC and AgNPs@Fe@CMC Nanocomposites

The AgNPs@CMC, FeNPs@CMC and AgNPs@Fe@CMC were separately prepared via the reduction co-precipitation method. In this method, 100 mL of an aqueous solution of metal salt (0.05M) was prepared and 2 g of CMC extract was added. The system was kept under stirring (500 rpm) at room temperature for 30 min. Thereafter, 0.5M of sodium borohydride was added to the solution containing the metal ion-loaded CMC under continuous stirring for 1 hour. The metal oxide loaded CMC was isolated, washed with distilled water, and dried in an oven at 60° C. for 24 hour. The silver nanoparticle-loaded CMC was labeled as AgNPs@CMC and iron nanoparticle CMC was labeled as FeNPs@CMC.
