This study presents a new double-layered TiO2 film containing a nanocrystalline under-layer and a uniform, sponge-like light scattering over-layer for dye-sensitized solar cells (DSCs) application. The over-layer is composed of 2-μm-diameter uniform aggregates, containing small nanoparticles with the average grain size of 20nm. X-ray diffraction reveals that the light scattering layer has a mixture...
Synthetic layered iron phenyl phosphate (Fe(OH)(C 6 H 5 PO 4 H) 1.6 (H 2 PO 4 ) 0.4 ·5.1H 2 O: FePP), which is composed of a multilayer alternating bilayer of phenyl groups of the phosphates and amorphous iron phosphate phase, was exfoliated in ethanol under ultrasonic irradiation. The exfoliation of FePP was recognized at 10–10,000ppm...
