“…Recently, plasmon‐transparent carboxylic functionalized CNTs thin films were used in delicate detection operations such as DNA biosensor for gender determination, ultrasensitive cancer markers, and photoelectrode in photoelectrochemical generation of hydrogen . This clearly confirmed the significance of the carboxylate functionalized CNTs thin films particularly if placed on renewable recyclable PGP platforms.…”

π‐Plasmon absorbance films of carboxylic functionalized multiwall carbon nanotubes (CNTs) coupled with renewable and recycled polycaprolactone grafted pectin (PGP) platforms as successful alternative for ordinary nondegradable platforms were investigated. Characterization of the synthesized carboxylic functionalized CNTs was performed using 1H NMR and attenuated total reflectance Fourier transform infrared for structural identification, thermogravimetric analysis and derivative thermogravimetric analysis for thermal stability, and X‐ray powder diffraction for crystal structure, whereas the characterization of prepared PGP was done by means of attenuated total reflectance Fourier transform infrared for chemical structure, differential scanning calorimetry for melting endotherms of polycaprolactone and high crystalline structure of PGP, and thermogravimetric analysis and derivative thermogravimetric analysis for thermal stability of PGP. Fabrication of water‐dispersed carboxylic functionalized CNTs coupled with PGP films was performed by casting technique in the presence of Ca2+ as cross‐linker. The thin films were tested for π‐plasmon absorbance using UV‐Vis spectrometry. Different fractions of carboxylic functionalized CNTs and PGP films demonstrated π‐plasmon absorbance broad peaks at λmax = 232 nm, which corresponded to 5.36 eV. The fabrication of novel films from renewable recycled PGP platform and advanced carboxylic functionalized CNTs properties will be the key features for many of next forthcoming technologies. The PGP considered as environment‐friendly and easily degradable platforms will be a successful alternative for conventional nondegradable electronic platforms, and water‐dispersed carboxylic functionalized CNTs with advanced properties will be finding accelerating executive applications.

“…23 The electronic structure of the CNT-oxide interface is degraded due to the chemical modication of the CNT surface, a step that is necessary to enable their appropriate dispersion. 20,24 The presence of TiO 2 as nanoparticles decorating the CNT surface leads to charges recombination upon interaction with the electrolyte. 25 The performance of TiO 2 -CNT coatings made by hydrolysis results in a photocurrent density of 0.05 mA cm À2 at 1.6 V RHE , 21 while the core-shell CNT-TiO 2 synthesised by gas phase process has shown a photocurrent density of 0.16 mA cm À2 at 1 V RHE .…”

“…The smaller crystal size of the catalyst possesses shorter carbon diffusion pathways for CNT formation. [ 3,9 ] The mild condition offers huge possibilities to prepare CNTs directly on fluorine‐doped tin oxide electrode for photo(electro)chemical and solar‐cell applications, [ 10,11 ] which suffers from low conductivity after high‐temperature treatment. [ 12,13 ] Of prime importance is that partial Fe substitution within 2D MnO 2 nanosheets remarkably enhanced their catalytic activity for the CNT growth at 400 °C.…”

The synthesis of carbon nanotubes (CNTs) is usually done by metallic catalysts with a gaseous carbon precursor at high temperature. Yet, mild synthesis conditions can broaden the application of CNTs and their composites. In the present work, it is unraveled why partially substituted Fe ions in 2D MnO2 nanosheets lead to the growth of CNTs at low temperatures of 400−500 °C. The local formation of Fe3C by carbon precursor explains the unusually high catalytic activity of 2D FexMn1−xO2 nanosheets for preparing CNTs. Finally, Fe3C is oxidized to Fe3C/FeOx yolk/shell morphology in ambient atmosphere after the CNT formation reaction. These results shed light on the development of novel catalyst materials that allow for efficiently prepare CNTs under mild conditions for their wider use in energy‐harvesting applications.
