Construction of Magnetically Retrievable g-C3N4/CeO2-Fe3O4-Reduced Graphene Oxide Composites With Enhanced Visible-Light Photocatalytic Activity And Antibacterial Properties
Construction of multi-interface contact step-scheme (S-scheme) photocatalyst is a promising pathway to achieve high-electron transfer efficiency for photodegradation estrone and congo red. In this paper, g-C3N4 is chosen as the main photocatalyst, CeO2 nanosheet with the unique Ce4+ → Ce3+ conversion performance and Fe3O4-Reduced graphene oxide are loaded onto the g-C3N4 surface to bulid 2D-2D magnetic photocatalyst. The 2D–2D magnetic photocatalyst structure imparts reusability by magnetic retrieval and at the same time Fe3O4-Reduced graphene oxide acts as an efficient host for g-C3N4/CeO2 composite photocatalyst. The photocatalytic performance is examined using etsrone and congo red. Photodegradation studies show the CeO2/g-C3N4/ Fe3O4- Reduced graphene oxide a composite catalyst can degrade 71% of estrone, 92% of congo red and 89% phenanthrene, Free radical scavenger test shows superoxide and hydroxyl radical species play a major role in the degradation. Furthermore, it is demonstrated that the magnetic CeO2/g-C3N4/ Fe3O4-Reduced graphene oxide possesses strong antibacterial properties against Proteus mirabilis and Escherichia coli. A three-factor-three-level Box–Behnken design (BBD) was selected to optimize three greatly influential parameters: light irradiation time (min), The quality of photocatalyst(mg) and pollution concentration(ppm) by response surface methodology. It is expected that CeO2/g-C3N4/ Fe3O4- Reduced graphene oxide can be used as a 2D–2D magnetic photocatalyst for to achieve its valorization, which have very broad development prospects in the field of environmental remediation or catalysis.
期刊介绍:
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
