ZnO and TiO2 are both well-known electron transport materials; however, an exact comparison of their performance, when fabricated under the same synthesis conditions, is missing in literature. Considering this, we introduced a viable electrospinning route for development highly polycrystalline nanofibers material (ETM) perovskite solar cells photocatalysts textiles. Thanks to effective tuning b...

Carbon nanofibers decorated with various metal oxide nanoparticles were fabricated by combining an electrospinning technique of bicomponent polymer mixture and a sol-gel reaction subsequent carbonization process. Electrospun consisting polyacrylonitrile (PAN) poly(vinyl pyrrolidone) (PVP) controllable diameters PAN/PVP core/shell types via phase-separation due to the immiscibility between two p...

TiO2-based nanofibers were synthesized using a sol-gel method and electrospinning technique. The as-spun composite fibers were heat-treated at different temperatures (500°C, 550°C, 600°C, and 650°C) and atmospheres (ammonia and nitrogen) for 4 h. The fibers had diameters of 50 to 200 nm and mainly featured anatase and rutile phases. The anatase phase decreased and the rutile phase increased wit...

In order to enhance the electron transport on the photoelectrodes of dye-sensitized solar cells, one-dimensional rutile nanorods were prepared using electrospun TiO2 nanofibers. The grain size of the nanorods increased with increasing temperature. Electrochemical impedance spectroscopy measurements revealed reduced interface resistance of the cells with the one-dimensional rutile nanorods due t...

Two important criteria of an ideal biomaterial in the field of stem cells research are to regulate the cell proliferation without the loss of its pluripotency and to direct the differentiation into a specific cell lineage when desired. The present study describes the influence of TiO2 nanofibrous surface structures on the regulation of proliferation and stemness preservation of adipose-derived ...

Titanium oxide (TiO2) nanofibers are interesting for environmental applications, particularly solar energy and water treatment, due to their physical properties, chemical stability, high activity, strong oxidation capacity. Here, we designed synthesized halloysite-TiO2 nanocomposite fibers by combining the electrospinning sol-gel methods. Halloysite was extracted at Tamra (norther-western part ...

Titanium dioxide (TiO2) is a well-studied photocatalyst that is known to break down organic molecules upon ultraviolet (UV) irradiation. Cellulose nanofibers (CNFs) act as an attractive matrix material for the suspension of photocatalytic particles due to their desirable mechanical and optical properties. In this work, TiO2–CNF composite films were fabricated and evaluated for photocatalytic ac...
