Cotton-derived 3D carbon fiber aerogel to in situ support Bi2O3 nanoparticles as a separation-free photocatalyst for antibiotic removal

Nitrogen-Doped Hierarchical Nanoporous Carbon Materials from Discarded Polyurethane Sponges via One-Step Double-Activation Method for Double-Layer Capacitors

“…Besides, there is an obvious hysteresis loop of adsorption and desorption at relative pressures of 0.4–0.9, which can be attributed to mesopores and the multilayer adsorption on the outer surface. The hierarchical porous structure facilitates high density charge storage by promoting double-layer capacitance and shortening the ion diffusion distance. , …”

“…The hierarchical porous structure facilitates high density charge storage by promoting double-layer capacitance and shortening the ion diffusion distance. 28,29 To further investigate the specific surface area and pore structure of the prepared carbon materials, it becomes imperative to determine their pore size distribution. Table 1 presents that the specific surface areas (SSAs) of NC, NPC-Z, and NPC-CZ are 36.5, 1018.1, and 1108.8 m 2 g −1 , respectively; activation significantly enhances SSA values as well as total pore volume (NC, 0.064 cc g −1 ; NPC-Z, 0.71 cc g −1 ; NPC-CZ, 0.62 cc g −1 ).…”

Biomass-based graphene aerogel for the removal of emerging pollutants from wastewater

“…136 Zhang et al synthesized a Bi 2 O 3 supported carbon fiber aerogel for continuous and stable removal of antibiotics without any separation operation. 14 Fang et al developed TiO 2 nanotube pillared graphene-based macrostructures for continuous removal of emerging pollutants from water. The prepared sample removed almost 86% of BPA at an initial concentration of 0.05 mg L −1 under Xe lamp irradiation in a continuous flow system.…”

“…Aerogel is a 3D highly porous structure and can be fabricated by substituting the liquid component by gas, typically air. Aerogels of various materials such as carbon fibers, 14 silica 15 and titania 16 have been highly investigated for water remediation and environment applications. Compared with other aerogel materials, graphene aerogel is superior because of its lightweight 3D porous structure consisting of 2D atomic layers which provides maximum specific surface area, lower density, high mechanical strength, chemical stability and greater tunability.…”

Construction of a carbon nanosphere aerogel with magnetic response for efficient oil/water separation

“…13,14 Currently, the oil/water separation adsorbents include nanocomposite particles,15 nanospheres, 16 composite membranes, 17 sponges, 18 aerogels, and so on. [19][20][21][22][23][24][25] An aerogel is a bulk porous material with a three-dimensional network structure, [26][27][28][29][30] which has been widely used as gas filter materials, photocatalysts, [31][32][33] catalyst carriers, conductive materials, 34,35 adsorbents and insulation materials in the field of environmental remediation. 36,37 As a kind of aerogel, the carbon aerogel possesses high porosity, large specific surface area, and excellent chemical stability and mechanical properties.…”
