The role of Vorasurf 504 surfactant in the production of large mesoporous carbon using solvent-free method and its application in the removal of emergent contaminants
This work reports using the solvent-free method for the first time in the literature using the surfactant Vorasurf504 (V504) to produce mesoporous carbons (MC). In addition to V504, resorcinol was used as a carbon source, and terephthalaldehyde as a cross-linking agent. Three materials were produced with different proportions of resorcinol: V504, 1:1 (R1V), 1:2 (R2V), and 1:3 (R3V). V504 enabled the production of large mesoporous carbon, mainly for the materials with higher proportions of surfactant. The average pore diameters of the materials varied between 5 and 29 nm, and the mesopore volumes were on the order of 0.922 cm3 g−1. The three produced materials were applied to remove emerging contaminants (EC) with different structural dimensions: paracetamol (PA), atrazine (AT), tenofovir (TF), and ceftriaxone (CF). During the contact test, R2V and R3V showed removals above 90 % for all EC. However, due to its limited mesoporosity, the R1V material had its removal capacity reduced for contaminants of larger structural dimensions. Through kinetic and isotherm studies for systems involving paracetamol and ceftriaxone, it was proven that, in fact, not only the specific surface area but also the pore size and pore volume influence adsorption. As a result of this study, large mesoporous carbon could be produced using a surfactant that has not previously been investigated for the solvent-free method. Furthermore, the materials produced can be used as effective adsorbents for emerging contaminants of various structural dimensions.
期刊介绍:
Microporous and Mesoporous Materials covers novel and significant aspects of porous solids classified as either microporous (pore size up to 2 nm) or mesoporous (pore size 2 to 50 nm). The porosity should have a specific impact on the material properties or application. Typical examples are zeolites and zeolite-like materials, pillared materials, clathrasils and clathrates, carbon molecular sieves, ordered mesoporous materials, organic/inorganic porous hybrid materials, or porous metal oxides. Both natural and synthetic porous materials are within the scope of the journal.
Topics which are particularly of interest include:
All aspects of natural microporous and mesoporous solids
The synthesis of crystalline or amorphous porous materials
The physico-chemical characterization of microporous and mesoporous solids, especially spectroscopic and microscopic
The modification of microporous and mesoporous solids, for example by ion exchange or solid-state reactions
All topics related to diffusion of mobile species in the pores of microporous and mesoporous materials
Adsorption (and other separation techniques) using microporous or mesoporous adsorbents
Catalysis by microporous and mesoporous materials
Host/guest interactions
Theoretical chemistry and modelling of host/guest interactions
All topics related to the application of microporous and mesoporous materials in industrial catalysis, separation technology, environmental protection, electrochemistry, membranes, sensors, optical devices, etc.
