Abstract
Environmental pollution resulted from antibiotic-containing effluent has gained much focus. Photocatalytic technology has been recognized as one of the promising candidates for solving this problem. Herein, A series of 0D/2D Ag3PO4/Nickel-Aluminum layered double hydroxide (NiAl-LDH) nanocomposites were fabricated via a room-temperature precipitation strategy. The physical and chemical properties of the obtained photocatalysts were systematically characterized. The photocatalytic performance of the fabricated photocatalysts was estimated by tetracycline hydrochloride (TCH) degradation under simulative visible light irradiation. Compared with a single component, the Ag3PO4/NiAl-LDH nanocomposites exhibited superior photocatalytic activity toward TCH degradation. The apparent kinetic constant of the optimized sample was 61.6 and 3.1 times higher than that of NiAl-LDH and Ag3PO4, respectively. Based on the analysis of X-ray photoelectron spectra, the measurement of band edge positions, active species capturing experiments and the qualitative analysis of hydroxyl radicals, the Z-scheme photocatalytic mechanism was proposed.
