“…[67] In the electrospinning process, the morphology and uniformity of the nanofibers are determined by an umber of parameters that can be separated into two main themes:1 )polymer/solution properties such as molecular weight, viscosity,c onductivity,s urfacet ension; 2) set-up parameters such as the electric field, the flow rate of the solution,a nd tip-to-collectord istance. [71] To increase the active surfacea rea of the TiO 2 nanofibers, the authors prepare different TiO 2 -based composite and co-doped nanofibers, such as graphene-TiO 2 , [72] BN-TiO 2 , [73] ZnO/TiO 2 , [74] CuO/TiO 2 , [75] and Ag/ TiO 2 , [76] by electrospinning. [68,69] In general, the elaboration of TiO 2 nanofibersb yu sing electrospinning involves the following three steps:1 )preparation of the electrospun solution with the titania precursor and ap olymer template;2 )electrospinning of the solution to obtain the composite nanofibers;3 )cal-cination of the as-prepared nanofibers to remove the polymer and to obtain the crystalline phase of the TiO 2 nanofibers.…”

Environmental and energy problems have drawn much attention owing to rapid population growth and accelerated economic development. For instance, photocatalysis, "a green technology", plays an important role in solar-energy conversion owing to its potential to solve energy and environmental problems. Recently, many efforts have been devoted to improving visible-light photocatalytic activity by using titanium dioxide as a photocatalyst as a result of its wide range of applications in the energy and environment fields. However, fast charge recombination and an absorption edge in the UV range limit the photocatalytic efficiency of TiO under visible-light irradiation. Many investigations have been undertaken to overcome the limitations of TiO and, therefore, to enhance its photocatalytic activity under visible light. The present literature review focuses on different strategies used to promote the separation efficiency of electron-hole pairs and to shift the absorption edge of TiO to the visible region. Current synthesis techniques used to elaborate several nanostructures of TiO -based materials, recent progress in enhancing visible photocatalytic activity, and different photocatalysis applications will be discussed. On the basis of the studies reported in the literature, we believe that this review will help in the development of new strategies to improve the visible-light photocatalytic performance of TiO -based materials further.

“…To date, the potential of Ti has not been experimentally evaluated. The only work that could be mentioned is about titanium oxide TiO 2 coating BN nanofibers . In comparison to uncoated nanofibers, a slight improvement of the H 2 uptake at room temperature was found (1.5 vs. 2 wt % H 2 .).…”

Boron Nitride for Hydrogen Storage

2018

Boron nitride, BN, for hydrogen storage emerged in the beginning of the millennium and there swiftly followed more than 15 years of efforts combining experimental laboratory works and to a greater extent computational predictions. BN has been considered mainly for the storage of molecular hydrogen, H2, by physisorption and/or chemisorption over a wide range of temperatures, that is, between −196 °C and 300 °C. Yet its potential has gone beyond the sorption of H2 as it has been also, although less extensively, involved in chemical H storage. The present review aims at giving a comprehensive overview of the main experimental results and findings as well as of the different avenues worth being explored. A key lesson of this survey is that boron nitride may turn out to be a promising material for hydrogen storage at room conditions provided all the predictions come true. The “ball” is now in the lab experimenters’ court.

“…The main difference between CNTs and CNFs is that CNFs lack a hollow cavity structure and have larger diameters and lengths compared to those of CNTs. These peculiar shaped nanomaterials with various stacking arrangements of graphene sheets, such as stacked platelet, herringbone and ribbon shapes, have been synthesized through chemical vapor deposition or electrospinning methods [119][120][121].…”
