This study describes the synthesis of delafossite, CuFeO2, as a primary photocatalytic material for hydrogen generation. A photoelectrode, CuFeO2/CuO/Cu, was prepared by combusting Cu foil dipped in FeCl3 ambient air. photoelectrode showed excellent optical behavior generation reaction from sewage water, producing 90 µmol/h H2. The chemical structure confirmed through XRD and XPS analyses, crys...

Material nanostructuring and optical phenomena on a nanoscale such as plasmonic effects light scattering have been widely studied for improving the solar-to-hydrogen efficiency of photoelectrochemical (PEC) water-splitting electrodes. In this work, we report method analyzing contributions from nanostructures enhancing PEC performances. Electromagnetic simulations are performed precise calculati...

DSSC (dye-sensitized solar cell) is a third-generation photovoltaic technology that can convert energy into electric current using photoelectrochemical mechanism. Photoelectrode one of the significant elements in DSSC, where photoexcited electrons are generated, and serves as an electron transport medium. Anatase titanium dioxide (TiO2) often used photoelectrode material because its excellent p...

This Review focuses on recent developments in the use of ZnO nanostructures for dye-sensitized solar cell (DSC) applications. It is shown that carefully designed and fabricated nanostructured ZnO films are advantageous for use as a DSC photoelectrode as they offer larger surface areas than bulk film material, direct electron pathways, or effective light-scattering centers, and, when combined wi...

A mesoscopic nitrogen-doped TiO2 sphere has been developed for a quasi-solid-state dye-sensitized solar cell [DSSC]. Compared with the undoped TiO2 sphere, the quasi-solid-state DSSC based on the nitrogen-doped TiO2 sphere shows more excellent photovoltaic performance. The photoelectrochemistry of electrodes based on nitrogen-doped and undoped TiO2 spheres was characterized with Mott-Schottky a...

Developing a high-performance photocatalyst and a photoelectrode with enhanced visible light harvesting properties is essential for practical visible light photocatalytic applications. Noble metal-free, highly visible light-active, elemental red phosphorus (RP) was prepared by a facile mechanical ball milling method, which is a reproducible, low cost and controllable synthesis process. The synt...

A new kind of bio-nanocomposite photoelectrode was fabricated through direct immobilization of the bacterial photosynthetic reaction center (RC) proteins on a nanocrystalline TiO2 matrix prepared by anodic electrodeposition. The near-infrared (NIR)visible absorption and fluorescence emission spectra displayed that structure and activity of the RC remained unaltered on the nano-TiO2 film surface...
