Addressing the environmental challenges posed by oil spills and industrial wastewater is critical for sustainable development. Graphene aerogels demonstrate significant potential as highly efficient adsorbents due to their high specific surface area, excellent structural tunability and outstanding chemical stability. Among available fabrication methods, the hydrothermal self-assembly technique stands out for its low cost, high tunability and good scalability.

Water purification has always been a critical yet challenging issue. In this study, an organic-inorganic composite membrane was developed using 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-oxidized bacterial cellulose (BC) nanofibers and hydroxyapatite nanowires (HAPNW) with tunable wettability for advanced membrane separation applications. The resulting free-standing TEMPO-BC/HAPNW filter membrane exhibited strong mechanical strength, high flexibility, exceptional deformability, and a high pure water flux of up to 800 L·m·h due to its porous architecture and inherent hydrophilicity.

The development of affordable ceramic membranes is essential for reducing expenses and optimizing the treatment of oily wastewater. There is an urgent demand for membranes that are not only affordable and easy to operate but also stable and capable of managing high fluxes to address the increasing volumes of oily wastewater. The significant production demands associated with many commercially available ceramic membranes, primarily due to the use of specialised raw materials and intricate processing methods, limiting their suitability for many wastewater treatment applications.

The rational use of solar energy to achieve photothermal conversion is an attractive strategy to promote the efficient removal of radioactive Cs and Sr from nuclear wastewater. Herein, a photothermal adsorbent of composite aerogel with three-dimensional porous structure is fabricated by integrating prussian blue analogues (PBAs) and straw biochar into the chitosan (CS) and waste leather scrap hydrolysate (WLSH) aerogel matrix (CS/WLSH/C/PBAs). The local heating effect generated by CS/WLSH/C/PBAs aerogel induce to generate steam, accelerating the enrichment of Cs and Sr in the solution, which increase their interaction with the CS/WLSH/C/PBAs and improves their adsorption rates and capacities.
