“…Synthesis was carried out, upon 120 mL/min 1:1 i‐C4H10:H2 flow, over catalyst with 17 wt % nominal metal load. After synthesis, raw CNT were treated with a 1 M solution of NaOH at 80 °C for Al2O3 support removal, while a solution at 37% of HCl at room temperature eliminated residual Fe‐nanoparticles . Produced CNT were multiwalled CNTs (MWCNT), as reported by transmission electron microscopy analysis, not shown for briefness.…”

The aim of this work is the synthesis of silicone foam containing carbon nanotubes (CNT) for oil spills remediation. The CNT silicone foams are obtained by foaming a solution of a silicone matrix with CNT filler (5.6 wt %) in presence of a Sn-based catalyst. Pristine and functionalized CNT have been used. All the obtained materials present a foam morphology with an open cell structure. Each foam is tested in four commonly used oils (kerosene, pump oil, naphtha, and crude oil). Among all, the foam filled with pristine CNT shows the highest sorption capacity (800 wt % in virgin naphtha) and an excellent reusability (up to 10 times).But, until now, none of the mentioned systems is entirely satisfactory because of certain problems, such as permanent hydrophilic nature, low flammability, and sorption efficiency. Moreover, many of them are complex, expensive, and bulky.Recently Chen et al. demonstrated a simple, inexpensive, versatile, and scalable process to prepare superhydrophobic and Additional Supporting Information may be found in the online version of this article.

“…Besides serving as a support, CNTs alone can be used as catalysts for some specific reactions, including methane and NO x decomposition [3,4], oxidative dehydrogenization of aromatic hydrocarbons and alkanes [5,6,7,8,9], oxidation of aniline [10], p-toluidine [11], and benzyl alcohol [12], catalytic wet air oxidation of phenol [13,14] and pcoumaric acid [15,16], aerobic oxidation of cyclohexane [17,18], ozonation of oxalic acid [19,20], selective oxidation of H 2 S [21], and heterogeneous hydroxylation of organics [22]. Nitrogen-doped CNTs were used as basic catalyst in Knoevenagel condensation [23] and CO oxidation [24] reactions.…”

The catalytic performance of multi-walled carbon nanotubes (MWCNTs) with different surface chemistry was studied in the decomposition reaction of H 2 O 2 at various values of pH and temperature. A comparative analysis of experimental and quantum chemical calculation results is given. It has been shown that both the lowest calculated activation energy (~18.9 kJ/mol) and the highest rate cons tant correspond to the N-containing CNT. The calculated chemisorption energy values correlate with the operation stability of MWCNTs. Based on the proposed quantum chemical model it was found that the catalytic activity of carbon materials in electron tran sfer reactions is controlled by their electron donor capability.

“…The sp 2 C fraction of sample AF2, whose representative point lies around the minimum of the ω G vs T M curve ( Fig. 3a), is approximately 59% [14]. Annealing of NTs at moderate temperatures produces a limited decrease of sp 3 hybridized C bonds [15].…”

A very simple model for the kinetics of oxidation of carbon Nanotubes (NTs) is proposed which is able to reproduce the main features of their measured kinetic thermal oxidation profiles. Based on this model the resistance to oxidation of NTs is found to decrease with increasing defect density and amorphous phases, i.e. sp 3 bonding component. This finding supports the validity of assumptions previously made to explain the correlation between results of Raman Spectroscopy (RS) and Kinetic Thermal Analysis (KTA) on NTs via a three-stage model, inspired to that proposed by Ferrari and Robertson for other nanocarbons.
