Cellulose Nanofiber-Reinforced MXene Membranes as Stable Friction Layers and Effective Electrodes for High-Performance Triboelectric Nanogenerators

“…It is noted that similar MXene–CNF–aerogel–PVDF and MXene–CNF-film–PTFE had also been reported. However, the former was not conductive to be an electrode, and the effective work of the latter lies on a PDMS substrate . The above discussion indicates that our MXene/CNF TENGs not only have shown advantages of device conformation (effective electrodes, robust friction layers, and high flexibility) but also exhibited comparable as well as stable output performances, , which is very promising for practical energy harvesting.…”

“…The alternated MXene films were previously used as friction layers but their mechanical properties were too weak to be used effectively as electrodes . It is noted that similar MXene–CNF–aerogel–PVDF and MXene–CNF-film–PTFE had also been reported. However, the former was not conductive to be an electrode, and the effective work of the latter lies on a PDMS substrate .…”

“…As an example, Ma’s group reported a stretchable TENG fabricated from 1D cellulose nanofibers (CNFs) integrated with an MXene dispersion as a liquid electrode in conjunction with standard silicon rubber as a triboelectrification layer . However, to the best of our knowledge, there have been few studies of pure MXenes or MXene-rich composites that simultaneously act as effective electrodes and triboelectrification layers (having electronegative or even electropositive characteristics) for high-performance output. − Such investigations could be helpful by precisely locating MXenes in the triboelectric series.…”

Sulfur vacancy modulated nickel-doped Co4S3hollow nanocube/nitrogen-doped V2CTxMXene nanosheet composites for optimizing the hydrogen evolution reaction

“…The characteristic hollow/mesoporous structure could endow it with continuous ion diffusion pathways and short ion transport. 26 As shown in the electron paramagnetic resonance (EPR) spectrum (Fig. 3(d)), Ni-Co 4 S 3 (S v )/N-V 2 CT x depicts obvious signals with a g value of 2.003, which is significantly higher than that of Ni-Co 4 S 3 /V 2 CT x , indicating that Ni-Co 4 S 3 (S v )/N-V 2 CT x possesses more unpaired electrons.…”
