Recently, the research on remediation of aqueous organic pollutants over visible-light-active photocatalysts has got much attention. Therefore, this study reports fabrication Co3O4-Bi2O3 heterojunction photocatalyst for photodegradation rhodamine B dye. The was synthesized by coprecipitation method and characterized XRD, EDS, SEM, TEM, TGA, FTIR. as-prepared utilized as a abatement It observed ...

Electrospinning of nanofibers with cyclodextrin (CD) is attractive because the produced fibers can potentially increase the efficiency of nanofibrous membranes by facilitating the complex formation with organic compounds and high surface area of the nanofibers. In this work, polyacrylonitrile (PAN) nanofibers functionalized with β– cyclodextrin (βCD) during an electrospinning process were used ...

The past three decades have witnessed extensive research in developing a range of non-metallic fused heterocyclic organic dyes for dye sensitized solar cells (DSSCs).

Sensitizers are responsible for the light harvesting and the charge injection in dye-sensitized solar cells (DSSCs). A fast dye-regeneration process is necessary to obtain highly efficient DSSC devices. Herein, dye-regeneration rates of two DSSC device types, that is, the reduction of immediately formed photo-oxidized sensitizers (ruthenium complex C106TBA and porphyrin LD14, k(ox)') by iodide ...

An efficient synthetic protocol to functionalize the cyanoacrylic acid anchoring group of commercially available MK-2 dye with a highly water-stable hydroxamate anchoring group is described. Extensive characterization of this hydroxamate-modified dye (MK-2HA) reveals that the modification does not affect its favorable optoelectronic properties. Dye-sensitized solar cells (DSSCs) prepared with t...
