“…Nanotubes (NTs) are a kind of one-dimensional (1D) materials with atomic layer thickness that have attracted much attention in comparison with their bulk counterparts due to their unique properties, which provide for prospective applications encompassing microelectronics, photovoltaics, gas sensing, electrochemical sensing, infrared photodetection, photocatalyst and biomedics, for example [1][2][3][4][5][6][7][8][9][10].…”

We investigate the electronic properties of blue-phosphorene nanotubes using density functional theory first-principle calculations, taking into account, in particular, the presence of atom vacancies in the structure. The study considers both zigzag and armchair achiral configurations and reports on the structure and the electron energy states of the nanostructure. Compared to pristine blue-phosphorene nanotubes, which exhibit values of the fundamental bandgap between one and two electron-volts. For atomic single vacancies, the incorporation of spin-polarization helps to identify the induction of localized mid-gap states in the blue phosphorene nanotubes. The difference of energy between the highest near-valence and lower near-conduction localized states is, approximately, of 0.5 eV. Also the increase of the single vacancies concentration leads to the formation of additional bands that change the energy gap of the system.

“…The quick recombination problem of photogenerated charge carriers (electron-hole pairs) reduces the quantum efficiency of the photocatalytic process. Therefore, in recent years, many authors have been designed and developed nanocomposites including TiO 2 to avoid this problem and the pairing effect of MWCNTs with TiO 2 has been presented to provide a synergistic effect which can enhance the overall reaction of the dyes photodegradation [14][15][16][17][18][19][20], also TiO 2 can combined with other materials to like multinano walled carbon nanotubes to obtain good performance as photocatalyst. The prepared nanocomposites were evaluated for the photodegradation of the Vat Green 1 and Dianix Blue Dyes under Sunlight, UV and Xenon sources as well as the degree of complete degradation of the two dyes were assessed.…”

Multi-walled carbon nanotubes (MWCNTs) were prepared using chemical vapour deposition (CVD) method. MWCNTs/titanium dioxide nanocomposites (MWCNTs/x%TiO 2 ) with different weight ratios of TiO 2 (x = 3, 6 and 10%) were synthesized using a simple modified evaporation method and used as a photocatalysts. Their photocatalytic activity investigated by studying the decontamination of two local textile dyes (Vat Green 1 and Dianix Blue Dyes) as an industrial organic pollutants commonly used in dyeing factories. The structure of the synthesized photocatalysts were characterized using XRD, SEM, diffused reflectance UV-Vis spectroscopic and N 2 adsorption-desorption method. Also, their optical band gaps were estimated, by as 3.51, 2.89, 2.80, 2.69 eV for MWCNTs and MWCNTs/x%TiO 2 respectively. The mineralization of Vat Green 1 and Dianix Blue dyes in presence of MWCNTs and MWCNTs/x%TiO 2 nanocomposites were investigated by determining the decrease in chemical oxygen demand (COD). In addition, the suggested possible mechanism of the photodegradation processes was studied.

“…Many applications of CNTs have been examined, as they are one of the representative nanomaterials produced since the discovery of CNTs by Iijima in 1991 [1]. Over 25 years, many research and review papers have been actively published [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. However, the application and commercialization of CNT-based products have been limited to luxury and expensive products [2,3] because the manufacturing process is complicated and high in cost [17][18][19].…”

A Review of Applications Using Mixed Materials of Cellulose, Nanocellulose and Carbon Nanotubes

2020

Carbon nanotubes (CNTs) have been extensively studied as one of the most interesting nanomaterials for over 25 years because they exhibit excellent mechanical, electrical, thermal, optical, and electrical properties. In the past decade, the number of publications and patents on cellulose and nanocellulose (NC) increased tenfold. Research on NC with excellent mechanical properties, flexibility, and transparency is accelerating due to the growing environmental problems surrounding us such as CO2 emissions, the accumulation of large amounts of plastic, and the depletion of energy resources such as oil. Research on mixed materials of cellulose, NC, and CNTs has been expanding because these materials exhibit various characteristics that can be controlled by varying the combination of cellulose, NC to CNTs while also being biodegradable and recyclable. An understanding of these mixed materials is required because these characteristics are diverse and are expected to solve various environmental problems. Thus far, many review papers on cellulose, NC or CNTs have been published. Although guidance for the suitable application of these mixed materials is necessary, there are few reviews summarizing them. Therefore, this review introduces the application and feature on mixed materials of cellulose, NC and CNTs.
