- W3168389966 abstract "• Heterostructure composite was constructed via in-situ growth of Ag 3 PO 4 on red mud. • The composite (APRM) is a new cost-efficiency catalyst for photo-Fenton reaction. • APRM holds excellent catalytic activity and outstanding stability in use. • S-scheme heterojunction can account for the charge transfer pathway in APRM. • The toxicity of TC-HCl could be weakened via photo-Fenton catalyzed by APRM. In our work, using industrial waste red mud (RM) as a host material to grow silver phosphate (Ag 3 PO 4 ), a low-cost and new heterogeneous Ag 3 PO 4 /RM (APRM) composite was successfully prepared through a facile in-situ deposition method. The characterization results demonstrated Ag 3 PO 4 nanoparticles uniformly deposited on RM to form P-O-Fe bonds, and a semiconductor heterostructure was constructed between the two nanocrystalline components of Ag 3 PO 4 and Fe 2 O 3 . The optimal composite of APRM-110 exhibited a remarkable photocatalytic activity for the degradation of tetracycline hydrochloride (TC-HCl) in photo-Fenton reaction. The enhanced photocatalytic performance and stability could be attributed to the S-scheme charge transfer in APRM-110, which accelerated the photo-generated carrier separation and then effectively restrained the photocorrosion of APRM-110. The APRM-110 composite held good reusability, stability and excellent settleability. The main intermediates were identified and the degradation pathway of TC-HCl in photo-Fenton reaction catalyzed by APRM-110 was proposed. The aquatic toxicity of TC-HCl solution could be effectively weakened by the photo-Fenton catalyzed by APRM-110. This work has designed a cost-efficiency and stable RM-based Ag 3 PO 4 composite, and as a highly effective catalyst for TC-HCl degradation in photo-Fenton reaction." @default.
