“…After the oxidation process of MWCNTs, additional adsorption bands were emerged (Figure 5, spectrum b). As seen, pronounced adsorption bands characteristic for CO observed stretching of aromatic ester, CO vibrational stretching of conjugated ketone, and OH vibrational stretching of alcohols were noticed at 1360, 1660, and 3440 cm −1 , respectively 57 . The emerge of these new IR adsorption bands indicated the surface functionalization of MWCNTs which is advantageous for polymer grafting.…”

Polyacrylic acid (PAA) is one of the most exciting hydrophilic polymers for water control and conservation; however, it suffers from poor mechanical properties during the agricultural applications. For that purpose a series of PAA-based multiwalled carbon nanotubes (MWCNTs) membranes have synthesized via a grafting process of MWCNTs using chitosan (CS) polymer as a binder. The fabricated membranes have spectroscopically characterized by different techniques to confirm the composite structure. The MWCNTs content into the PAA membranes has played a pronounced effect on water absorptivity, swelling behavior, and mechanical properties. PAA membrane has showed a fourfold increase in yield-stress by the addition of 3 wt% PAA/CS/MWCNTs, while preserving a 91% of water absorptivity of PAA membrane. The soil applications of the PAA/CS/MWCNTs membranes have showed remarkable improvements in soil moisture content compared to the PAA membrane. This study provides a promising pathway for future field applications, especially in arid lands.

“…ReNPs can also be integrated on various supports via wet impregnation. Dobrzańska-Danikiewicz et al [160,177] made gas or liquid sensors based on MWCNTs decorated with ReNPs. The MWCNTs were fabricated by catalytic chemical vapor deposition of C 2 H 4 on a silicon substrate at 750 °C for 45 min.…”

Over the past decade, metal nanoparticles (MNPs) have attracted extensive attention due to their unique physiochemical properties that make them highly applicable in various fields such as chemical sensing, energy storage, catalysis, medicine, and environmental engineering. Their physiochemical properties depend drastically on the MNP size and morphology, which are largely determined by their synthesis methods. Research on MNPs predominantly focused on coinage metals (Au, Ag and Cu), but in the last decade research on metals with a relatively high melting temperature such as Pd, Co, and Re has seen rapid increases, mainly driven by their potential applications as catalysts. This paper presents the recent advances on different synthesis techniques of Co, Pd, and Re nanoparticles, their resulting nanostructures, as well as existing and potential applications.

Carbon nanotubes (CNTs) are receiving a great deal of attention as a catalyst support for different energy applications, due to their high surface area and high conductivity. Recent literature studies have shown that the application of CNTs mainly depends on their surface functionalization process. Typically, pristine CNTs (as produced) have no functional groups, which is usually considered as an obstacle to their widespread application. In this chapter, we highlight the different techniques used to functionalize the surface of CNTs, including physical and chemical functionalization processes. We show the advantages and the drawbacks of the different functionalization processes. Additionally, we explain in detail the different techniques used to characterize the CNTs before and after functionalization processes. Furthermore, we focus on polymer wrapping techniques of CNTs to create active nanocomposite materials for energy applications, in particular the applications in the agriculture field to fight pollution and make farming activity easier and more efficient.
