“…Keeping this in mind, present work reports the development of SiO 2 -a-CNT hybrids and studies the system as remover of Rh-B. It has been seen that though when a-CNTs are added in to SiO 2 matrix the dominating removal mechanism changes from adsorption to photo-catalysis while as per previous report a-CNTs are very good absorber of dyes [31]. Thus overall it is a synergetic effect of adsorption and catalysis for the removal of the dye.…”

“…As reported in previous work [31], certain amount of ferrocene (C 5 H 5 ) 2 Fe and ammonium chloride (NH 4 Cl) were mixed in ratio 1:2. The mixture was placed in mortar to grind well and then it was kept in an oven in a glass beaker for 30 minutes at 225 0 C. To remove the impurity, the mixture was washed thoroughly with deionized water and diluted HCl.…”

Present work reports the synthesis of amorphous carbon nanotube-Silica (a-CNT-SiO 2 ) hybrids by a simple cost friendly method. The as synthesized samples were characterized by instruments like XRD, FESEM, FTIR spectroscopy, and Raman spectroscopy. The XRD spectra con rm the proper phase formation of the sample whereas the FESEM micrographs reveal that the samples have been developed in the cluster form.FTIR spectra reveals that there are several absorption peaks present these are mainly assigned to the Si-Si, Si-O, Si-H, C-C, C=C, C=O, C-H n or OH bonds.Raman spectra of the pure and hybrid samples have also been studied in detail.From the application point of view both the pure and hybrid samples have shown good e cacy in removing dyes like rhodamine B with e ciency over 90 % within just 45 minutes. Kinetic studies con rmed that the reaction mostly followed pseudo 1 st order mechanism

“…When decorated with SnO 2 , controllably damaged by argon ions on the sidewall, or combined with RGO on carbon cloth/polyethylene terephthalate substrates, aCNTbased nanostructures have good field-emission characteristics [66,83,135]. Furthermore, the amorphous structure of aCNTs makes them a better simulant of kerogen than graphitic CNTs [136].…”

Carbon nanotubes (CNTs) have rapidly received increasing attention and great interest as potential materials for energy storage and catalyst fields, which is due to their unique physicochemical and electrical properties. With continuous improvements in fabrication routes, CNTs have been modified with various types of materials, opening up new perspectives for research and state-of-the-art technologies. Amorphous CNTs (aCNTs) are carbon nanostructures that are distinctively different from their well-ordered counterparts, such as single-walled and multi-walled carbon nanotubes (SWCNTs and MWCNTs, respectively), while the atoms in aCNTs are grouped in a disordered, crystalline/non-crystalline manner. Owing to their unique structure and properties, aCNTs are attractive for energy storage, catalysis, and aerospace applications. In this review, we provide an overview of the synthetic routes of aCNTs, which include chemical vapor deposition, catalytic pyrolysis, and arc discharge. Detailed morphologies of aCNTs and the systematic elucidation of tunable properties are also summarized. Finally, we discuss the future perspectives as well as associated challenges of aCNTs. With this review, we aim to encourage further research for the widespread use of aCNTs in industry.

By using sol-gel method, Nb/SnO2 gel was prepared,and spin coating method was used to coat on glass substrates, which dried and calcined to obtain a homogeneous Nb / SnO2 composite films.Under the same experimental conditions, the different doping amount of nickel, calcination temperature on the structure and morphology of Nb/SnO2 film were discussed. By using XRD, IR, SEM and other testing methods, the structure and morphology of Nb / SnO2 composite film were characterized.At 500 °C, the film particle had high crystallization and small size,and the surface of the film was well-distributed.Its optical and electrical properties were tested by the ultraviolet-visible spectrophotometer and four-probe resistivity meter.UV-Vis spectra showed that Nb / SnO2 film absorbance in the near ultraviolet region had increased significantly, but the absorbance showed a downward trend with the increasing amount of Nb5+ doped;Conductivity analysis showed: Nb5+ doping amount of 8% (the amount of material), the conductivity of Nb/SnO2 composite films was best.
