“…6d, Table S2), implying the low inactivation probability of photo-induced electrons and leading to high photocatalytic activity. The photocatalytic recyclability and stability of photocatalyst are important for the applications 36 . Moreover, the enhancement of the photocurrent in the ZnO/Fe 2 O 3 /g-C 3 N 4 composite is attribute to the heterojunction formation between g-C 3 N 4 and ZnO/Fe 2 O 3 , which promotes a valid separation of photo-generated holes and electrons.…”

A series of ZnO/Fe 2 O 3 /g-C 3 N 4 photocatalysts were synthetized by impregnation of g-C 3 N 4 with Zn(NO 3 ) 2 ·6H 2 O, and Fe(NO 3 ) 2 ·9H 2 O followed by calcination. The morphology, chemical composition, and structure of the resulted materials were carefully analyzed by various characterization techniques. The photocatalytic performance of ZnO/Fe 2 O 3 /g-C 3 N 4 composites was evaluated based on the H 2 evolution from water splitting reaction. The results showed that the ZnO/Fe 2 O 3 /g-C 3 N 4 composite can effectively produce more H 2 than pure g-C 3 N 4 when irradiated under visible-light. H 2 production rate over 3-ZnO/Fe 2 O 3 /g-C 3 N 4 composite was of 25 μmol·h −1 , which is 4 times higher than that obtained in the presence of pure g-C 3 N 4 , clearly showing a significant improvement of the photocatalytic activity of the prepared nanocomposite. This result was attributed to the formation of a heterojunction between g-C 3 N 4 and ZnO/Fe 2 O 3 , which delayed the recombination of holes-electrons pairs and resulted in a remarkable increase in photocatalytic performance.

“…The shortcoming is that the photogenerated carriers of single g-C3N4 can easily recombine, which hinders its practical application. Some strategies such as doping other elements [57,58], loading cocatalysts [59][60][61], tuning the morphology, and forming heterojunctions with other semiconductors have been developed to address this issue [62][63][64][65][66]. We obtained porous g-C3N4 (Pg-C3N4) by thermal decomposition of thiourea and urea.…”

The spent fluid catalytic cracking catalyst (FCC) has been loaded with different content of V 2 O 5 and TiO 2 through a modified-impregnation method. X-ray Diffraction (XRD), ultraviolet-visible spectrophotometry (UV-Vis), Scanning Electron Microscope (SEM), and Fourier Transform Infrared spectroscopy (FT-IR) are used to characterize the structure and morphology of these samples. Their photocatalytic activity was evaluated by degradation of methylene blue (MB) solution under 300 W Xenon lamp irradiation. The interplanar spacing of the zeolite Y (111) plane is affected by the amount of the loaded V 2 O 5 on spent FCC catalyst. The (111) plane of spent FCC catalyst loaded with V 2 O 5 and TiO 2 sample is 1.404 nm, which is higher than that of the zeolite Y (1.395 nm). The amount of adsorption of MB and the photocatalytic activity for the degradation increased with increasing the interplanar spacing of the (111) plane of sample. We fabricated of spent FCC catalyst composites by loaded V 2 O 5 and TiO 2 , which effectively solved the spent FCC catalyst disposal problem. The efficiency of the developed sample provides a potentially economical way of degrading MB.
