شرح پروژه
سلام درصد وزنی ترکیب rGO در سنتز زیر را میخواستم
For designing and preparing rGO-Co3O4/ZnO NCs, 1.18 g of CoCl2·6H2O and 0.3 g of CO(NH2)2 have been dissolved in 10 ml rGO solution (1mg/mL) and 20 ml of ZnO NPs (1mg/mL) and stirred for 2 h. The transfer of this mixture into a Teflon-lined autoclave was performed, and then it was heated for 24 hours to reach 80 °C. After cooling the solution, the precipitate was separated from the solution by centrifuge and washed with absolute ethanol and distilled water to remove impurities. The drying operation of the precipitate of this process was performed under a vacuum for 8 hours at 60 °C, and its calcination was done for 4 hours at 200 °C. Finally, the NCs of rGO that was modified with ZnO and Co3O4 NPs were obtained.
