Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 10, 2024

Abstract Graphitic carbon nitride (g‐C 3 N 4 ) has witnessed tremendous research interest due to its narrow bandgap, intrinsic 2D structure, and abundant raw materials. Although g‐C some shortcomings such as low specific surface area, poor conductivity rapid charge carries recombination, various modification methods are constantly emerging enhance potential application value in photocatalysis. Increasing the crystallinity of is an effective strategy improve in‐plane separation efficiency. However, it also reported that amorphous possesses a higher adsorption activation ability over reactants richer functional groups than crystalline . Which type more suits photocatalysis, which method suitable for boosting activity two types , respectively? Based on these issues, recent advances preparation properties summarized, their performance improvement strategies overviewed thoroughly. Upon systematic comparison analysis, respectively, proposed. Their applications summed up especially environment remediation energy conversation. Finally, ongoing opportunities future challenges photocatalysis territory taken consideration.

Graphitic Carbon Nitride Modified with 2-Aminothiophene-3-Carbonitrile to Boost Molecular Dipole and n → π* Electronic Transition for Photoreduction of Carbon Dioxide

ACS Applied Nano Materials, Journal Year: 2023, Volume and Issue: 6(15), P. 14513 - 14526

Charge-transfer dynamics and light utilization efficiency are two critical factors that significantly impact the catalytic performance of a photocatalyst. Therefore, developing reasonable method to enhance these aspects is valuable strategy for creating efficient photocatalysts. In this study, we fabricated donor–acceptor (D–A) structure by modifying graphitic phase carbon nitride (g-CN) nanosheets with 2-aminothiophene-3-carbonitrile (ACT). The introduction ACT altered dipole moment g-CN extended conjugated system g-CN, thereby enhancing n → π* electronic transition. These improvements in molecular effectively enhanced charge-transfer efficiency. addition, greatly improved CO2 adsorption capacity nanosheets. Experimental results showed g-CN-ACT0.05 exhibited best photocatalytic reduction performance, CO evolution rate 8.27 μmol g–1 h–1, which was eight times higher than unmodified g-CN. This research serves as reference catalysts high activity reduction.
