2. Experimental Section 2.1. Preparation of Fe3O4@C9 Nanocomposite The CMK-9 was prepared by using mesoporous silica KIT-6 as the template, following the procedures mentioned elsewhere [16]. A total of 0.3 g of CMK-9 was mixed with 30 mL 1 M HNO3 acid and stirred for 24 h at 25 °C to functionalize the surface of CMK-9. The mixture was further sonicated for 2 h at 60 °C.
