Recent developments in the synthesis of electrospun nanomaterials and their potential prospects energy environmental applications are discussed detail.

Hydrogen is an attractive alternative to fossil fuels in terms of environmental and other advantages. Of the various production methods for H2, photocatalysis requires further development so that it can be applied economically on industrial scale. One- two-dimensional nanostructures both pristine modified forms have shown great potential as catalysts generation H2. We review here recent developments these nanostructure their efficiency H2 under UV/visible/simulated solar light. Despite much...

Growing energy demands are driving people to generate power in every possible way. New sources needed plug the gap. There is a growing interest distributed generation due its remarkable advantages such as flexibility, reliability, adaptability and minimal transmission losses. Thermoelectric generators (TEGs) one source that relies on thermal for electricity generation. The current review focusses design optimization of TEGs maximize output from available sources. basic principle...

Conductive polyanilines are synthesized by doping with inorganic and organic acids, namely Hydrochloric acid (HCl) ±10-camphor sulfonic (CSA). The direct current (DC) conductivities (σDC) found to be about 9.5 ′ 10-8, 1.8, 95.8 S/cm for PANI base, PANI(HCl) PANI(CSA), respectively. σDC is measured down a temperature of ~100 K the apparent change in activation energies 98.16, 74.40, 57.24 meV HCl, CSA dopings less dependent near room temperature, further decrease strongly dependent.

The review presented below summarizes the up-to-date research efforts in using one-dimensional TiO2 nanomaterials dye-sensitized solar cells. A brief account of methods synthesis anisotropic as well their photovoltaic performance DSCs was summarily presented. usefulness materials scattering layer also surveyed.

Additive manufacturing (AM) is integrated into almost each industry, with an objective to improve product functionality and decrease costs. Ever since from its introduction four decades ago, AM technologies have used numerous kinds of materials in polymers composite create complex 3D structures which were impossible manufacture through conventional techniques. However, many concerns remain for widespread applications 3D-printed materials, include inhomogeneous distribution particles,...

Techtonic plate-like nano structures synthesized by electrospinning and were employed for photocatalytic degradation. The possible photodegradation has been explained based on the band edge position.

Electrospinning is one of the simplest techniques for obtaining polymer nano fibers. Nanofibers have large surface area to volume ratio and hence excellent application potential in sensors, filter design etc. Polyaniline (PANI) well-known widely studied conducting polymer, which however, insoluble many common organic solvents difficult process. PANI its base form non conductive but it can be made by protonating with an acids such as hydrochloric acid (HCl) or camphor sulphonic (CSA)....

We report the use of highly porous, dense, and anisotropic TiO(2) derived from electrospun TiO(2)-SiO(2) nanostructures through titanate route in dye-sensitized solar cells. The titanate-derived high surface areas exhibited superior photovoltaic parameters (efficiency > 7%) comparison to respective nanomaterials commercially available P-25.

The surface areas of electrospun fibers/rice grain-shaped nanostructures TiO2–SiO2 composites were further enhanced after transforming them into thorn or sponge shaped titanates via selective leaching SiO2, which was reported by our group previously [RSC Adv., 2012, 2, 992]. In this study, we report on their application in photocatalytic activity (PCA) when juxtaposed with photoluminescence (PL). Two defect related bands are observed PL and origin is discussed relation to calcination,...
