“…Previous studies about dye adsorbents focused on not only classic materials like activated carbons (Al-Degs et al 2008), but also several novel materials such as mesoporous carbons (Zhuang et al 2009;Teng et al 2012;Tripathi et al 2013), carbon nanotubes (Yan et al 2005;Wang et al 2012), titanium dioxides (Bourikas et al 2005), and mesoporous silicas (Wang and Li 2006;Huang et al 2011). The adsorption efficiency can be enhanced by chemical modification introducing activated organic groups [amino (Ho et al 2003;Donia et al 2009), pyridine (Yan et al 2006), surfactants (Faki et al 2008), polyelectrolytes (Joo et al 2009), etc.…”

“…Good performance of inorganic adsorbents usually bases on high surface area, large pore volume, and suitable pore diameter. Materials meeting all these conditions have received increasing attention (Zhuang et al 2009;Huang et al 2011;Teng et al 2012;Tripathi et al 2013). One critical challenge for preparing ordered morphology and pore structures is to find suitable templates.…”

“…One critical challenge for preparing ordered morphology and pore structures is to find suitable templates. Several molecules can play the role of template (or structure directing agent), such as amines (Naik et al 2007;Aprile et al 2009), block copolymers (Jin et al 2009;Zhuang et al 2009;Paik et al 2010;Teng et al 2012;Tripathi et al 2013), polyelectrolytes (Viva et al 2012), dendrimers (Hukkamaki and Pakkanen 2003;Knecht and Wright 2004), etc. Polyamidoamine (PAMAM), or sometimes called ''artificial protein'' (Bielinska et al 2002), is a series of dendrimers containing various amounts of-NH 2 groups.…”

Efficient treatment of solutions and solid wastes containing Rhodamine B (RB), a common dye with potential carcinogenicity and sometimes used illegally in food industry, is of great importance because inappropriate treatment may lead to serious human and environmental risks. A novel nanomaterial, the mesoporous silica nanosheets prepared via electrospinning and calcination are applied to the adsorption of RB from aqueous solutions in this work. This sheet-like material is superior to classic powder adsorbents in recoverability, while good availability and stability favor its practical application. The effects of key parameters such as system pH, stirring rate, initial concentration, and contact time are studied. The adsorption isotherm type and the kinetic characteristic are analyzed. The results show that the mesoporous SiO 2 nanosheets are efficient in removing RB from aqueous phase, presenting great potential to become a practical dye adsorbent. Regeneration experiments show that this novel adsorbent can be activated by ethanol extraction process. This study provides the academic field with a successful application case of nanostructured materials, which can be applied to a wider range of dyes similar to RB in physicochemical properties, showing prosperous value in advanced environmental purification.

“…In further research, Si et al [88,89] utilized the electrospun PAN/PBZ as composite carbon precursor to investigate the dye adsorption capacities. Teng et al [43] prepared the mesoporous ACNF by sol-gel/electrospinning process by using phenolic resin precursor as a carbon source and triblock polymer Pluronic F127 as a template and then carbonization and removal of SiO 2 . The mesoporous ACNFs were used as highly efficient adsorbents for large dye molecules (methyl thionyl chloride, methyl orange, acid red 1).…”

In the past few decades, removing or controlling the concentration levels of the pollutants including toxic gases, heavy metal ions, and organic contaminants in environmental systems has attracted tremendous attention. Among the numerous approaches, adsorption is considered to be one of the most versatile and promising approach in removing pollutants due to its convenience, ease of operation, simplicity of design, and universal in use. Electrospun nanofibers have unique properties such as large surface area, tailored pore structure, high porosity, and flexibility of surface functionalization, therefore could be used as advanced adsorbents for contaminant removal. Importantly, nanofiber-based adsorbents are expected to possess strong adsorption capacity, fast kinetics, and good reproducibility due to the unique structure of nanofibers. In this chapter, we summarize recent progress in the development of electrospun nanofibrous membrane-based adsorbent for the removal of toxic gases and pollutants in aqueous solution (heavy metal ions and organic contaminants), describe the design of the nanofibrous materials, and discuss their adsorption performance in detail. This chapter might trigger further development and evolution of adsorption based on electrospun nanofibers as one potential to ease the environmental pollution problem.

“…Surfactants play a key role in the synthesis of porous materials because they can act as sacrificial templates [87,88]. In the process of synthesizing MOFs, surfactants can be used as a sacrificial template to obtain micropores and mesopores structure.…”
