“…Compared to arc discharge and laser ablation, CVD is more attractive because it is a relatively low-cost and less hazardous chemical synthesis technique that requires a low synthesis temperature, allowing the use of renewable feedstocks and enabling an easy industrial scale-up. In contrast, arc discharge and laser ablation methods allow less control over the processing parameters, consume higher energy, and give a lower percent yield of the product [3].…”

AbstractWater hyacinth (WH) is a noxious weed. Its rapid growth can clog waterways, causing widespread ecological and environmental threats as well as power generation and irrigation issues. In the present study, water hyacinth was utilized as a precursor to synthesize multiwall carbon nanotubes (MWCNTs) using a simple chemical vapor deposition method. FESEM-EDS revealed that the synthesized MWCNTs had noodle-like, dense, and rough surfaces. TEM confirmed that MWCNTs had a bamboo-like structure with the diameter of 30–40 nm, and the wall thickness of approximately 7 nm. The interlayer distance was found to be approximately 0.34 by XRD. Raman spectra displayed three major bands of MWCNTS: D-band at 1,340 cm−1, G-band at 1,596 cm−1, and (D + G)-band between 2,783 and 2,953 cm−1. The ratio of the D-to-G band intensity was 0.94 ± 0.03, indicating that the synthesized MWCNTs had well degree of graphitization. Electrochemical measurement results of the prepared MWCNTs cathode for aluminum–air battery showed that MWCNTs exhibited higher energy capacity than commercial graphite. Collectively, this study shows that water hyacinth could be used effectively as a precursor for the production of MWCNTs, thus successfully converting the noxious weed into high value-added materials.

“…CNTs can be synthesized from graphite, plastic polymers, charcoal byproducts and biochar by laser ablation, chemical vapor deposition, arc discharge, microwave irradiation, among others [22,111]. SWCNTs can be metallic or semiconductors depending on their atomic arrangement and their diameter [110].…”

Nowadays, carbon‐based materials applied to the development of chemically modified sensors have been highlighted once they can generate methods with high sensitivity, stability, conductivity, accuracy and low cost. Hence, these sensors have been used in environmental monitoring in aneco‐friendlyy, sensitive, fast, efficient, inexpensive and robust way. In this review, firstly we described about carbon‐based materials and their derivatives, followed by the chemically modified carbon‐based sensors manufacturing overview and their applications in environmental analytical chemistry related to inorganic and organic compounds determinations. Future perspectives on trends of the carbon‐based materials applications in the sensor modifications are also described.

“… 76 Natural clays have also been deployed as catalysts with the advantages of their inherently strong acidity, ion-exchange capability, adsorption, and large surface area. 77 Siliceous breccia was utilized as a natural catalyst for manufacturing CNTs without any pretreatment process through the chemical vapor deposition technique (750 °C, 30 min); 78 siliceous breccia with iron oxide-hydroxides functioned as catalysts for dissociating the precursors of hydrocarbon and producing the CNTs. 78 Pumice (a volcanic rock) and laterite (a clay material) as natural catalysts have been evaluated for fabricating graphitized CNTs; these CNTs were employed as reinforcement constituents in nanocomposite materials.…”
