Abstract

There are still challenges to eliminate and reduce the harmful persistent organic pollutants (POPs) in the water, especially the dye-based POPs. Two big obstacles the Ag₃PO₄ photocatalyst faces are serious carrier recombination and photocorrosion, which presents a limitation for its application in water purification. Therefore, in this work, a novel Ag₃PO₄/SrTiO₃ heterojunction was synthesized by a simple in situ deposition method. Ag₃PO₄/SrTiO₃ 10:1 exhibits the highest photocatalytic activity with rhodamine B (RhB) degradation of 98.8% in only 20 min and methyl orange (MO) degradation of 97.5% in 80 min under simulated sunlight irradiation, which is much higher than that of pure Ag₃PO₄ and the mixed photocatalysts. During the photocatalytic reaction, h⁺ and •O₂⁻ are the main active species, and the charge transfer path is satisfied with the Z-scheme mechanism. Additionally, the possible degradation pathways of RhB and MO were proposed by analyzing the intermediate products via HPLC-MS.

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
