Water pollution by organic dyes, such as methylene blue (MB), has become an increasingly important issue. g-C3N4/SiO2 aerogel composites exhibit potential for removing dyes but are still limited their small specific surface area and low photochemical efficiency. In this study, we propose approach preparing combining sol-gel calcination processes to optimize the materials’ adsorption photocatalytic synergistic effects structural design. composites, layered g-C3N4 nanosheets grew uniformly on inside SiO2 three-dimensional network structure. Among them, 20-g-C3N4/SiO2 showed highest MB degradation efficiency, with a of 151.5 m2/g pore diameter 11 nm. Under visible light, it achieved 92% at dosage 0.2 g/l 50 mg/l initial concentration, which was 6.1 times rate 3.4 aerogel. Moreover, material exhibited excellent cyclic stability degraded 85% after three cycles. The effectively adsorbed focused surfaces because superior capacity facilitated in situ under light. This process efficient high concentrations MB, indicating application value removal from water.

Recent Progress of Multifunctional Silica Aerogel Composite Materials: From Fabrication Strategies to Versatile Applications

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Май 28, 2025

Silica aerogels are considered promising materials for use in harsh environmental conditions due to their low density, high specific surface area, porosity, and thermal conductivity. However, traditional silica face some obstacles widespread practical applications insufficient mechanical robustness, stability, limited functionalization. The addition of functional fillers polymer is an effective method enhance the physical properties multiple functionalities aerogels. This review aims summarize recent progress fabrication, properties, aerogel composites. Various methods components used modify aerogels, including fibers, carbon, materials, summarized introduced, followed by a description multifunctional management, ablation resistance, oil/water separation, more. Finally, perspectives future research directions development advanced composites also discussed highlighted.
