FeVO4/g-C3N4 Heterojunction: Characterization and Photocatalytic Approach Towards the Synthesis of N-(Pyridin-2-yl)cinnamamide Analogues
Nano photocatalysts based on semiconductors have received significant attention because of their tendency to catalyse organic processes. To enhance the photocatalytic activity of the highly effective metal vanadate FeVO4, FeVO4 and graphitic C3N4 nanocomposites were created. A range of complementary techniques, such as powder X-ray diffraction (XRD), N2 adsorption–desorption, scanning/transmission electron microscopy, energy dispersive X-ray analysis (EDAX), Fourier transform infrared spectroscopy (FTIR), diffuse reflectance ultraviolet-visible spectroscopy (UV-DRS), X-ray photoelectron spectroscopy (XPS), and photoluminescence, were employed for characterisation. Morphological studies revealed that the FeVO4 nanoparticles were randomly distributed on the surface of C3N4. Optical studies revealed the photocatalytic performance of the nanocomposites in the visible-light region. The nanocomposite was applied to the synthesis of N-(pyridin-2-yl)cinnamamide analogues under blue LED illumination. The reaction reached a maximum yield of 92% after 4 h. The photocatalytic mechanism was evaluated, and reusability studies were conducted, which established the stability of the composite for up to five consecutive runs.
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.
