2 SLAC National Accelerator Laboratory, 2575 Sand Hill Road, Menlo Park, CA 94025, USA. As a final point, the photocatalytic test showed that the photocatalytic activity increased 26% for TiO 2/ B. 1 European XFEL, Albert-Einstein-Ring 19, D-22761 Hamburg, Germany. In addition, the molecular modelling evidenced that the sensitization of the semiconductor improved the light absorption in the visible range of the spectrum. The interaction of the dyes with a TiO 2 slab model and their adsorption energies were determined through computational simulations. Here, three main anthocyanins were identified, being cyanidin-3-rutinoside the most abundant constituent ( ca. The qualitative and quantitative analyses of the anthocyanins were carried out using high-performance liquid chromatography with photodiode array detection (HPLC-DAD), which provided the total content anthocyanin equivalent to delphinidin chloride (TAEDC) per mL of the extract, of 10.0 ± 0.8 µg TAEDC/mL. The sensitization process was verified by diffuse reflectance spectroscopy (DRS). quantum efficiency translation in English - English Reverso dictionary, see also 'quantum chromodynamics',quantum electrodynamics',quantum electronics',quantum flavourdynamics', examples. reported an internal quantum efficiency (IQE) greater than 100 in a photoelectrochemical cell consisting of a monolayer of PbS QDs strongly coupled to an atomically flat anatase surface (), although the external quantum efficiency (EQE) and power conversion efficiency (PCE) were small due to the limited absorption of the. TiO 2 thin films, sensitized by an anthocyanins-rich extract of a common species found in the Colombian Caribbean region ( Bactris guineensis fruits), were used for the photocatalytic degradation of methylene blue. Two recent reports have shown progress toward these goals.
