“…To further investigate the binding states and chemical components of obtained samples, deconvoluted XPS spectra have been shown in Figure 4. For the Ti 2p spectra of MoS 2 /Ti 3 C 2 T x @NC (Figure 4a), the fitted peaks at around 455.0 and 457.7 eV can be assigned to Ti 2p 1/2 , and another two peaks centered around 460.6 and 463.5 eV correspond to Ti−O and Ti−C, respectively [30] . Notably, the peak positions do not change compared with MoS 2 /Ti 3 C 2 T without NC coating.…”

Although it is a promising sodium storage material due to its excellent electrochemical activity, small bandgap, and large interlayer spacing, layered molybdenum disulfide (MoS2) suffers from poor rate capability and degraded cycling life, resulting from its serious aggregation upon preparation, sluggish reaction kinetics, and structure expansion during cycling. To address these issues, a polyethyleneimine (PEI)‐assisted fabrication approach was developed for the rational synthesis of an interconnected framework with nitrogen‐doped carbon‐confined MoS2 nanosheets/Ti3C2Tx MXene (MoS2/Ti3C2Tx@NC), where the PEI could guide the uniform growth of MoS2 on Ti3C2Tx and the self‐generated NC simultaneously enhanced its synergistic coupling with MoS2/Ti3C2Tx, thus contributing to the improvement of charge transfer, diffusion kinetics, and structural integrity of the hybrid electrode. Consequently, the desired MoS2/Ti3C2Tx@NC delivered impressive sodium storage performance, demonstrating high reversible capacities of 397.3 and 206.8 mAh g−1 at 0.1 A g−1 after 100 cycles and 0.5 A g−1 after 500 cycles, respectively. Moreover, electrochemical kinetics analysis and charge storage mechanism manifested that high capacitive contribution, facilitated Na+ transport pathways, and synergistic electronic coupling between MoS2/Ti3C2Tx and NC contributed to the superior sodium storage performance.

Influence of the Hydrophilic Surface of Nanofiber Support on the Performance of Hybrid Supercapacitors

et al. 2021

Concerns associated with global warming and the depleting reserves of fossil fuels have highlighted the importance of high−performance energy storage systems (ESSs) for efficient energy usage. ESSs such as supercapacitors can contribute to improved power quality of an energy generation system, which is characterized by a slow load response. Composite materials are primarily used as supercapacitor electrodes because they can compensate for the disadvantages of carbon or metal oxide electrode materials. In this study, a composite of oxide nanoparticles loaded on a carbon nanofiber support was used as an electrode material for a hybrid supercapacitor. The addition of a small amount of hydrophilic FeN@GnP (Fe− and N−doped graphene nanoplates) modified the surface properties of carbon nanofibers prepared by electrospinning. Accordingly, the effects of the hydrophobic/hydrophilic surface properties of the nanofiber support on the morphology of Co3O4 nanoparticles loaded on the nanofiber, as well as the performance of the supercapacitor, were systematically investigated.

“…Furthermore, TMDs have been widely investigated for electronic devices and energy storage systems due to their higher electrical conductivity than that of oxides, distinctive electronic structure, 2D sheet-like morphology, high surface area, and multivalent oxidation states of transition metal ions [ 57 ]. TMDs are a new lineage of 2D nanosheets, typically having general formula as MX 2 (where, M: transition metal and X: chalcogen), for example molybdenum disulphide (MoS 2 ) [ 58 ] or diselenide (MoSe 2 ) [ 59 ], nickel selenide (NiSe) [ 60 ], cobalt selenide (CoSe) [ 61 ]. In addition, MXenes, discovered in 2011 and known as 2D carbides and the nitrides of transition metals, have been considered a favourable electrode material for supercapacitors due to their hydrophilicity, outstanding electrochemical properties and high electrical conductivity [ 58 , 62 , 63 ].…”

Sustainable biomass has attracted a great attention in developing green renewable energy storage devices (e.g., supercapacitors) with low-cost, flexible and lightweight characteristics. Therefore, cellulose has been considered as a suitable candidate to meet the requirements of sustainable energy storage devices due to their most abundant nature, renewability, hydrophilicity, and biodegradability. Particularly, cellulose-derived nanostructures (CNS) are more promising due to their low-density, high surface area, high aspect ratio, and excellent mechanical properties. Recently, various research activities based on CNS and/or various conductive materials have been performed for supercapacitors. In addition, CNS-derived carbon nanofibers prepared by carbonization have also drawn considerable scientific interest because of their high conductivity and rational electrochemical properties. Therefore, CNS or carbonized-CNS based functional materials provide ample opportunities in structure and design engineering approaches for sustainable energy storage devices. In this review, we first provide the introduction and then discuss the fundamentals and technologies of supercapacitors and utilized materials (including cellulose). Next, the efficacy of CNS or carbonized-CNS based materials is discussed. Further, various types of CNS are described and compared. Then, the efficacy of these CNS or carbonized-CNS based materials in developing sustainable energy storage devices is highlighted. Finally, the conclusion and future perspectives are briefly conferred.
