摘要
Abstract In this study, an economical ZnFe 2 O 4 @BC composite was successfully synthesized using pomelo peel biochar through a simple one‐pot thermal‐calcination roasting method. The combination of biochar and ZnFe 2 O 4 was confirmed by FTIR, XRD, Raman, TEM, and XPS analysis, confirming that the successful insertion of carbon into the oxygen sites of the ZnFe 2 O 4 lattice, forming C−O bonds. The incorporation of biochar resulted in a high specific surface area, providing more active sites for catalytic reactions, enhancing electron transport, effectively separating electron‐hole pairs, increasing light capturing capacity, and restraining the leaching of metals. The Zn vacancy acted as an electron acceptor, promoting electron transfer in the catalyst by reducing the lowest unoccupied orbital position. Additionally, various reaction parameters such as solution pH, iron content, catalyst dosage, and H 2 O 2 volume were investigated to elucidate their effects on the degradation performance. This study proposes a novel method for synthesizing carbon‐coated metal oxide semiconductors, which shows great potential for environmental and energy‐related applications.
