Abstract
The Type II heterojunction, characterized by its favorable band alignment, facilitated efficient charge separation in photocatalysts. Concurrently, oxygen vacancies can enhance light absorption and activated reactants, thereby improving photocatalytic efficiency. This study presented the synthesis of Bi-TCPP/Bi2S3 heterojunction photocatalysts, which were rich in oxygen vacancies, using a green, one-pot method. The composite exhibited superior photoelectrochemical and photocatalytic reduction properties, achieving a rate constant of 0.03829 min−1 for Cr(VI) reduction and a remarkable reduction rate of 95.73%. After five cycles, the photocatalytic activity remained above 91.30%, demonstrating excellent stability and efficiency in reducing persistent pollutants. This work introduced a novel strategy for photocatalyst design and made a significant contribution to the fields of environmental remediation and green chemistry.
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.
