C3N4 modified with single layer ZIF67 nanoparticles for efficient photocatalytic degradation of organic pollutants under visible light

Ultrafast conversion of carcinogenic 4-nitrophenol into 4-aminophenol in the dark catalyzed by surface interaction on BiPO4/g-C3N4 nanostructures in the presence of NaBH4

“…Regardless, the photocatalytic effectiveness of g-C 3 N 4 is still limited due to several issues including the fast recombination of electron/hole charges and low adsorption capacity. 21,22 To limit the recombination of charges and enhance the catalytic ability of g-C 3 N 4 , the surface modification though metal doping 23 or non-metal doping processes 24 were extensively reported. In terms of 4-nitrophenol reduction, Pd, Ag, Au doped g-C 3 N 4 have been utilized to improve the catalytic activity of 4-nitrophenol reduction.…”

Surface Physicochemistry Modification and Structural Nanoarchitectures of g‐C3N4 for Wastewater Remediation and Solar Fuel Generation

“…[ 190 ] In another study, the construction of g‐C 3 N 4 core–shell structure with the addition of a PDA sphere template resulted in the presence of an inseparable interface between core and shell that managed the transmission of photogenerated carriers smoothly. [ 191,192 ] Meng et al. added that the photocurrent of PDA@CN was improved as a result of the successful transfer of photo‐induced electrons and holes due to the slightly smaller arc radius than that of bulk g‐C 3 N 4 .…”

[193] The synergistic effect of PDA on g-C 3 N 4 with the addition of Ni-Co/LDH improved photocatalytic activity by favoring delocalized electron, adhesive action, and photosensitivity, thus enhancing the photocatalyst ability for light acquisition.…”

“…The addition of metal‐organic framework, called zeolitic imidazole framework (ZIF)‐ZIF67 nanoparticles, that wrapped the curly layer of g‐C 3 N 4 , formed a core–shell structured photocatalyst for degradation of tetracycline. [ 192 ] The performance test revealed 4.7 times higher efficiency and reaction rate, compared to pristine g‐C 3 N 4 ; attributable to the synergistic effect between g‐C 3 N 4 and ZIF‐8, where the charge carrier separation and transfer were improved based on the enhanced temperature‐programmed reduction (TPR) analysis and the reduced EIS results. Apparently, an increase in the concentration of pollutants resulted in lower degradation efficiency, mainly because of the high amount of pollutants adsorbed on the surface of the photocatalyst and insufficient oxidizing species.…”

Research Progress of Metal Organic Frameworks/Carbon‐Based Composites for Microwave Absorption

“…The experimental results showed that ZIF‐8/CS composite had good adsorption property and excellent photocatalytic degradation effect under alkaline condition. Su et al [ 107 ] synthesized monolayer ZIF‐67‐C 3 N 4 composite with uniform distribution and applied it to photocatalytic degradation of methylene blue under visible light. The investigation revealed that 2.57 g ZIF‐67 with 0.3 g C 3 N 4 exhibited superior photocatalytic activities.…”
