Fabrication of 3D Graphene-Silk Elastic Aerogels for Sustainable and Efficient Removal of Organic Dyes from an Aqueous Medium

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 14, 2025

Water pollution by dyes is a serious environmental issue of modern society that needs to be addressed effectively. Herein, promising adsorbent, i.e., 3D composite aerogel, was developed using reduced graphene oxide and silk fibroin (rGO-SF) via hydrothermal freeze-drying techniques. The efficiency the prepared aerogel toward methylene blue (MB) dye adsorption explored in batch experiments. A study revealed capacity rGO-SF120 as 249.89 mg/g dye. also selectively adsorbs MB over other dyes, such rhodamine B (RhB) orange (MO). process mainly chemical (as data fitted well both pseudo-second-order Elovich kinetic models) followed Langmuir model, indicating it formed single layer on its surface. Overall, an effective potential candidate for treating dye-loaded water with high efficiency.

Efficient removal of heavy metals and other toxic metal pollutants from wastewater is essential to protect human health the surrounding vulnerable ecosystems. Therefore, significant efforts have been invested in developing practical sustainable tools address this issue, including high-performance adsorbents. In respect, within last few years, graphene-based aerogels/xerogels/cryogels (GBAs) emerged drawn attention as excellent materials for removing recovering harmful valuable different aqueous media. Such an upward trend mainly due features aerogel combined with properties graphene derivatives aerogel's network, GBAs' unique three-dimensional (3D) porous structure, high porosity, low density, large specific surface area, exceptional electron mobility, adjustable rich chemistry, remarkable mechanical features, tremendous stability. This review offers a comprehensive analysis fundamental aspects phenomena related application GBAs removal. Herein, we cover all types (bottom-up) synthesized GBAs, true microporous aerogels well 3D open-cell interconnected mesoporous macroporous aerogels, foams, sponges. Indeed, provide insights into understanding suitability such important by revealing mechanisms involved factors inducing controlling highly selective behavior these distinctive Besides conventional adsorptive pathways, critically analyzed ability electrochemically capture (i.e., electrosorption) their efficiency detoxification through reductive adsorption-reduction-readsorption). We also covered reusability aspect (GAs)-based adsorbents, which strongly linked outstanding stability efficient desorption captured metals. Furthermore, view numerous environmental benefits, development magnetically recoverable GAs highlighted. Moreover, shed light on potential scalable implementation evaluating performance continuous processes while highlighting versatility demonstrated remove multiple contaminants along Finally, provides readers accessible overview critical discussion major recent achievements regarding applications GAs-based adsorbents ions Along our recommendations suggestions future work new research directions opportunities, aims serve resource researchers field treatment inspire further progress towards next-generation expanding application.
