Magnetic Carbon Quantum Dots/Iron Oxide Composite Based on Waste Rice Noodle and Iron Oxide Scale: Preparation and Photocatalytic Capability.

ABSTRACT: To provide an economical magnetic photocatalyst and introduce an innovative approach for efficiently utilizing discarded waste rice noodle (WRN) and iron oxide scale (IOS), we initially converted WRN into carbon quantum dots (CQDs) using a hydrothermal method, simultaneously calcining IOS to obtain iron oxide (FeO_x). Subsequently, we successfully synthesized a cost-effective, magnetic CQDs/FeO_x photocatalytic composite for the first time by combining the resulting CQDs and FeO_x. Our findings demonstrated that calcining IOS in an air atmosphere enhanced the content of photocatalytically active α-Fe₂O₃, while incorporating WRN-based CQDs into FeO_x improved the electron-hole pair separation, resulting in increased O₂
