Synthesis of a hybrid material consisting of magnetic iron-oxide nanoparticles and carbon nanotubes as a gas adsorbent

Solvothermal in situ synthesis of Fe3O4-multi-walled carbon nanotubes with enhanced heterogeneous Fenton-like activity

“…More importantly, CNTs can serve not only as supports but also as components with synergistic and hybrid properties [17][18][19]. Successful loading of Fe 3 O 4 nanoparticles onto the outer surface of CNTs have been performed through the following techniques: high-temperature decomposition method [20], hydrothermal or solvothermal process [21,22], polymer wrapping and the layer-by-layer assembly method [23], electrostatic interaction [24][25][26], and wet chemistry [27,28]. These techniques have demonstrated to be useful to synthesize Fe 3 O 4 nanoparticles and CNTs hybrid materials.…”

Simultaneous determination of ascorbic acid, acetaminophen and codeine based on multi-walled carbon nanotubes modified with magnetic nanoparticles paste electrode

“…A and B can be divalent, trivalent, or quadrivalent cations including magnesium, zinc, iron, manganese, aluminum, chromium, cobalt, titanium, and silicon. Spinel ferrites are commercially essential materials because of their excellent structural, magnetic and electrical properties [16,17]. ZnFe 2 O 4 is one of the most important ferrite binary oxides with ferromagnetic property.…”

Microwave-Assisted Preparation of Carbon Nanotubes with Versatile Functionality

“…CNT exhibit impressive potentials in many applications such as electrical interconnects, (Kreupl et al 2004;Li et al 2003) thermal interface materials, (Biercuk et al 2002;Liu et al 2004) high-performance fibers, (Koziol et al 2007;Vigolo et al 2000), environmental monitoring (Lee, Sun, and Ling 2009;Lee et al 2010), and health & biotechnology (Ghule et al 2007) so on. Although the theoretical intrinsic electrical, thermal, and mechanical properties of an individual CNT are extraordinary, synthesized CNTs in reality are far from being defectfree.…”

“…Fig. 1 represents schematic of CNTs interaction with microwaves (Lobach et al 2002;Liu, Gao et al 2007;Lee et al 2010;Chajara et al 2010). …”

“…heating temperature and time period of microwave, various types and amounts of oxidative reagent) were investigated. The synthesized hybrid material was used as a gas adsorbent, consisting of magnetic iron-oxide nanoparticles (MINPs) and CNTs (Lee et al 2010). These hybrid materials were resulted from the electrostatic interaction between MINPs and the surface of microwave-assisted acidified MWNTs as shown in Fig.…”
