Ionic Liquid-Assisted Synthesis of Ag3PO4 Spheres for Boosting Photodegradation Activity under Visible Light

In this work, a simple chemical precipitation method was employed to prepare spherical-like Ag3PO4 material (IL-Ag3PO4) with exposed {111} facet in the presence of reactive ionic liquid 1-butyl-3-methylimidazole dihydrogen phosphate ([Omim]H2PO4). The crystal structure, microstructure, optical properties, and visible-light photocatalytic performance as-prepared materials were studied detail. addition liquids played crucial role forming morphology IL-Ag3PO4 sample. Compared traditional material, intensity ratio {222}/{200} facets XRD pattern significantly enhanced, indicating main on surface advantageous for facilitating charge carrier transfer separation. light-harvesting capacity larger than that Ag3PO4. activity samples evaluated by degrading rhodamine B (RhB) p-chlorophenol (4-CP) under visible light. photodegradation efficiencies 1.94 2.45 times higher RhB 4-CP removal, respectively, attributing synergy from enhanced photoabsorption. Based active species capturing experiments, holes (h+), superoxide radical (•O2−) visible-light-driven photodegradation. This study will provide promising prospect designing synthesizing liquid-assisted photocatalysts high efficiency.
