“…Specifically, the recent literature has concentrated on the MXene composites for electrocatalysts, such as the overlay of g-C3N4 and Ti3C2 nanosheets (Figure 9) composites (TCCN) as a catalyst for ORR process [159]. The Ti 3 C 2 MXene-based catalyst has shown excellent ORR activity and stability in the basic medium [160,161]. Through a sandwich-like form comprising of titanium atoms at the terminals or the surface layer and carbon atoms at the innermost layer, the catalyst is a flawless model system for the interpretation of the ORR active sites of this type of 2D layer-by-layer catalysts.…”

MXene is deemed to be one of the best attentive materials in an extensive range of applications due to its stupendous optical, electronic, thermal, and mechanical properties. Several MXene-based nanomaterials with extraordinary characteristics have been proposed, prepared, and practiced as a catalyst due to its two-dimensional (2D) structure, large specific surface area, facile decoration, and high adsorption capacity. This review summarizes the synthesis and characterization studies, and the appropriate applications in the catalysis field, exclusively in the energy storage systems. Ultimately, we also discussed the encounters and prospects for the future growth of MXene-based nanomaterials as an efficient candidate in developing efficient energy storage systems. This review delivers crucial knowledge within the scientific community intending to design efficient energy storage systems.

“…11 Prior art literature mentioned several successful modifications of RGO. For example, preparation of nitrogen doped RGOtitanium dioxide (TiO 2 ) for photocatalytic hydrogen evolution 12 ; combination of nanopowder of graphene, bismuth telluride (n-Bi 2 Te 3 ) with flexible polymer supported ITO glass 13 ; functionalization of RGO using ethylenediamine for lithium-sulfur battery 14 ; N-(trimethoxysilylpropyl) ethylenediamine triacetic acid to enhance the state of dispersion of RGO in water and polar organic solvents 15 ; β-cyclodextrin for electrochemical sensing of imidacloprid 16 ; 2,6-diamino pyridine for the detection of trinitrophenol, 17 and so forth. However, reports have also been found, where functionalized-RGO (f-RGO) was incorporated as a nanoreinforcing agent to improve the ductility and strength of the polymer matrix.…”

In this report, smart polyurethane-polystyrene interpenetrating polymer network (IPN)-based nanocomposites were fabricated using simultaneous polymerization technique with different doses of functionalized reduced graphene oxide (f-RGO). RGO was functionalized with monoglyceride of sunflower oil in the presence of toluene diisocyanate. Successful functionalization of RGO was supported by Fouriertransform infrared spectroscopy, X-Ray diffraction, and transmission electron microscopy analyses. Most interestingly, the fabricated IPN-based nanocomposites showed significant enhancements in mechanical (tensile strength: 165%; elongation at break: 198%; toughness: 340%) and thermal (thermally stable up to 262 C) properties upon incorporation of 1 weight% of f-RGO. Moreover, the fabricated nanocomposites exhibited outstanding chemical resistance, self-cleaning behavior through surface hydrophobicity (static contact angle: 125.6-136.5), multi-stimuli responsive shape memory effect (100% recovery within 33-44 s by microwave and 265-308 s by sunlight) and thermally actuated artificial muscle-like behavior. Therefore, the studied smart nanocomposites with the aforementioned properties hold significant potential for possible advanced applications.

“…[ 12,13 ] However, the photogenerated electrons and holes coexisting in TiO 2 , can make the probability of recombination very high and leads to lower rates of desired chemical transformation with respect to absorbed light energy. [ 14 ] Moreover, the non‐porous TiO 2 with polar surface exhibits low absorption ability for non‐polar organic pollutants. Li et al.…”

Highly stable and efficient coaxial electrospun fibers of polyvinyl alcohol (PVA) and polylactic acid (PLA) nanocomposite filled with titanium dioxide (TiO2) nanotubes areaccomplished for natural sunlight‐driven photocatalytic dye degradation. The coaxial electrospinning process generates well‐defined concentric cylinder‐like morphology, with the polymeric core and sheath phases, with TiO2 present only in the outer phases. The nanofibers are characterized for their coaxial morphology and the distribution of TiO2 in the sample is monitored through EDAX studies. Coaxial electrospinning process influences the polymeric structural and functional performances, regulates the crystallization kinetics, and ensures the entanglement of TiO2 nanopowders without allowing them to leach out. Photodecomposition of Rhodamine B and methylene blue dye are observed by the UV–visible studies and ≈80% and ≈85% degradation is achieved respectively after 8 h. A higher efficiency of degradation is achieved for the TiO2 nanocomposites, due to the photocatalytic activity of the TiO2 semiconductors, and also because of its presence in the sheath phase. The efficiency of dye degradation is correlated with the mechanical and dynamic mechanical properties of the fibers and with the typical fiber morphology and spinning mechanism. While the dye molecules get trapped in the porous sites of composite fibers, the TiO2 radicals initiates the photocatalysis process. The current technology is promising in manipulating flexible, durable, and environmentally friendly polymer nanocomposite fibers for industrial wastewater purification.
