Advanced Functional Materials, Год журнала: 2023, Номер 33(23)

Опубликована: Март 17, 2023

Abstract Multifunctional separation membrane is usually realized by multi‐component collaborative construction, which makes the preparation method complicated and uncontrollable. Herein, a novel multifunctional photocatalytic prepared vacuum self‐assembly of single seaweed‐like g‐C 3 N 4 photocatalyst. The gives certain roughness, large specific surface area, excellent hydrophilicity abundant transport channels. Through systematic study, exhibits five oil‐in‐water emulsions with maximum flux 3114.0 ± 113.0 L m −2 h −1 bar for 1, 2‐dichloroethane‐in‐water (Dc/W) emulsion efficiency 97.4 0.1% chloroform‐in‐water (C/W) emulsion. In addition, area narrow bandgap render visible light absorption characteristics accelerate e − ‐h + pairs rate, giving degradation antibacterial properties. shows good eight different pollutants, among effect rhodamine B (RhB), methylene blue (MB), crystal violet (CV) were ≈100%. against E. coli S. aureus also close to 100%. After 35 consecutive separations C/W 10 degradations RhB, still maintains performance. This long‐lasting broad application prospects in complex wastewater purification.

The Collision between g‐C₃N₄ and QDs in the Fields of Energy and Environment: Synergistic Effects for Efficient Photocatalysis

Small, Год журнала: 2023, Номер 19(14)

Опубликована: Янв. 2, 2023

Abstract Recently, graphitic carbon nitride (g‐C 3 N 4 ) has attracted increasing interest due to its visible light absorption, suitable energy band structure, and excellent stability. However, low specific surface area, finite response range (<460 nm), rapid photogenerated electron–hole (e − –h + pairs recombination of the pristine g‐C limit practical applications. The small size quantum dots (QDs) endows properties abundant active sites, wide absorption spectrum, adjustable bandgap, but inevitable aggregation. Studies have confirmed that integration QDs not only overcomes these limitations individual component, also successfully inherits each advantage. Encouraged by advantages, synthetic strategies fundamental QDs/g‐C composites are briefly elaborated in this review. Particularly, synergistic effects analyzed comprehensively, including enhancement photocatalytic performance avoidance Then, applications fields environment described further combined with DFT calculation reveal reaction mechanisms. Moreover, stability reusability analyzed. Finally, future development solution existing problems prospected.
