Amorphous copper oxide (Cu(II)) nanoclusters function as efficient electrocatalysts for the reduction of carbon dioxide (CO2) to monoxide (CO). In addition promoting electrocatalytic activity, Cu(II) act cocatalyts CO2 photoreduction when grafted onto surface a semiconductor (light harvester), such niobate (Nb3O8–) nanosheets. Here, photocatalytic activity and reaction pathway Cu(II)-grafted Nb3O8– nanosheets was investigated using electron spin resonance (ESR) analysis isotope-labeled...
Inorganic/organic nanocomposite counter electrodes comprised of sheetlike CoS nanoparticles dispersed in polystyrenesulfonate-doped poly(3,4-ethylenedioxythiophene (CoS/PEDOT:PSS) offer a synergistic effect on catalytic performance toward the reduction triiodide for dye-sensitized solar cells (DSSCs), yielding 5.4% power conversion efficiency, which is comparable to that conventional platinum electrode (6.1%). The electrochemical impedance spectroscopy (EIS) and cyclic voltammetry...
A copper-and-zinc (Cu–Zn) alloy material was synthesized using a vacuum sealing method, in which evaporated zinc reacted with copper film or nanoparticles to form homogeneous Cu–Zn alloy.
A visible-light-sensitive tin sulfide photocatalyst was designed based on a ubiquitous element strategy and density functional theory (DFT) calculations. Computational analysis suggested that monosulfide (SnS) would be more efficient than SnS2 as photocathode for hydrogen production because of the low ionization potential weak ionic character SnS. To test this experimentally, nanoparticles SnS were loaded onto mesoporous electrode using wet chemical method, bandgap synthesized quantum dots...
Improving the electro-catalytic activity of graphene has recently been subject intense research for high efficiency flexible energy storage and conversion devices. We report synthesis a large scale film by CVD method its functionalization with HNO3 electrochemical electrode in DSSCs. found that on enhances tri-iodide reduction rate three times dye sensitized solar cell compared to pristine graphene. The X-ray photoelectron spectroscopy (XPS) ultra-violet photoemission (UPS) studies confirm...
The 316 L stainless steel is one of the most commonly available commercial implant materials with a few limitations in its ease biocompatibility and long-standing performance. Hence, porous TiO(2)/ZrO(2) nanocomposite coated over steels was studied for their enhanced performance terms corrosion resistance, following sol-gel process via dip-coating technique. surface composition porosity texture to be uniform on substrate. Biocompatibility studies coatings were investigated by placing...
Heterogeneous bilayered semiconductor thin films were fabricated using p-type CaFe2O4 and n-type BiVO4 for photocatalytic overall water splitting. The interface of the layers was modified with Co3O4 a platinum co-catalyst. resulting bulk heterojunction film, which composed Co3O4/BiVO4/Pt/CaFe2O4/Pt on substrate, produced both oxygen hydrogen under visible-light irradiation in absence applied bias potential or sacrificial agents. Furthermore, balanced absorbed photon number between shown to...
Next-generation electrochemical energy storage materials are essential in delivering high power for long periods of time. Double-layer carbonaceous provide density with low due to surface-controlled adsorption. This limitation can be overcome by developing a low-cost, more abundant material that delivers and density. Herein, we develop layered C3N4 as sustainable charge supercapacitor applications. It was thermally polymerized using urea then protonated various acids enhance its contribution...
In this study, an effective method of slow hydrolization metal alkoxide (e.g., Ti(C4H9O)4) in ethanol–water system was systematically investigated and used to finely control the deposition titania on carbon colloids. A model adsorption–hydrolization precursors during coating process rationally built for first time interpret usability facilitate its further extension. Using strategy, form supported nanocrystals or layers colloids (TiO2/C, C@TiO2) successfully tailored. Meanwhile, dispersed...

Electropolymerized one-dimensional PEDOT nanofibers were firmly attached to flexible EFG sheet affording high catalytic activity electron conductivity. PEDOT/EFG electrode-based DSSCs showed an energy...
