Carbon Nanoparticles-Decorated Carbon Nanotubes

Abstract

Multi walled carbon nanotubes (MWcnts) were decorated by activated carbon nanoparticles of resorcinol-formaldehyde aerogels. carbon nanospheres and MWcnts were mixed by equal mass ratios for different durations. The products were characterized by Raman spectroscopy, thermal gravimetric analysis, nanoscanning electron microscopy, transmission electron microscopy and x-ray diffraction. The results indicated that a significant decoration with carbon nanoparticles occurred onto the MWcnts. Carbon nanotubes (CNTs) drew a remarkable attention from their first discovery. This is attributed to their unique features, such as mechanical properties, electric properties, thermal stability, high chemical resistance and large surface areas 1. As a result of these characteristics, they became strong candidates for numerous applications; including catalytic processes, water treatment, drug delivery, gene transfer, transparent conducting membranes and electrochemical analysis 2-7. The idea of CNT decoration was introduced to widen their applications in different fields. It was reported in various works of literature that it was possible to decorate CNTs with either organic compounds or metallic nanoparticles 8-10. The importance of carbon aerogels is assigned to their hierarchical porous properties, which makes them suitable for use in numerous applications 11-14. For example, carbon aerogels are utilized in catalyst support, separation tools, eclectic supercapacitor materials and battery construction 15,16. It is noteworthy to mention that, to the authors' knowledge, the carbon-carbon decoration of multiwall carbon nanotubes (MWCNTs) by carbon nanoparticles (CNp) was not tackled in literature. Therefore, in this work, we disclose our method of decorating MWCNTs with resorcinol-formaldehyde activated carbon aerogel (RFA) CNp. The hybrid carbon nanoproducts will be characterized by various devices for tracking the changes of outcome carbon nanoproducts.

Separation of Benzene/Cyclohexane Mixtures by Pervaporation Using Poly (Ethylene-Co-Vinylalcohol) and Carbon Nanotube-Filled Poly (Vinyl Alcohol-Co-Ethylene) Membranes

“…This fact reveals that the CNTs are well exfoliated and homogenously distributed in the E-VOH matrix. Similar results were also observed by Tang et al [51,52] on the investigation of rhodamine B-decorated grapheme as a reinforcement in polyvinyl alcohol composites (RhB-G/PVA). This result confirms that of the DSC analysis and indicates a perfect adhesion between CNT nanoparticles and E-VOH matrix.…”

Preparation of cerium oxide–MWCNTs nanocomposite bulk modified carbon ceramic electrode: a sensitive sensor for tamoxifen determination in human serum samples

“…The XRD peaks have good consistency with standard diffraction patterns (JCPDS) of the CeO2 with cubic uorite structure[22]. The broadening of diffraction peaks at about 26° and 44° could be assigned to the (002) and (100) planes of the hexagonal graphite structure of the MWCNTs[23].…”

Three-Dimensional Interpenetrating Network Phase-Change Composites with High Photothermal Conversion and Rapid Heat Storage and Release

“…A slight bulge in the diffraction peak of B-GA at 26.40°proves that B-GA shows a slight graphite property with the introduction of CNTs and CSs. 35,36 The high and sharp diffraction peak of PEG indicates that it has good crystallinity and high purity. The crystallinities of PEG in composites (GA-PEG and B-GA-PEG) are evaluated based on the strong diffraction peak of 19.20°for the deduction of background absorption.…”
