Photoelectrochemical Measurement of Phthalic Acid Adsorption on Porous TiO2 Film Electrodes
A new adsorption measurement method based on photoelectrochemical oxidation principle has been developed. The method can be used to directly quantify the amount of adsorbates at TiO2 electrode surface in a sensitive and accurate manner. The adsorption of phthalic acid on TiO2 was studied as a test case. The relationship between the amount of the adsorbate at TiO2 surface and the concentration o...
متن کاملModified Titania Films for Photoelectrochemical Applications
TiO2 is recognized as a photocatalytic material and has been widely used because of its high functionality, long –term stability and non-toxicity. [1]However, because the band gap of pure TiO2 for anatase crystalline phase is as high as 3.2ev, TiO2 shows only high reactivity under ultraviolet light. In order to make the better use with ideal energy source, sunlight, people have tried several mo...
متن کاملDirect in Situ Measurement of Charge Transfer Processes During Photoelectrochemical Water Oxidation on Catalyzed Hematite
Electrocatalysts improve the efficiency of light-absorbing semiconductor photoanodes driving the oxygen evolution reaction, but the precise function(s) of the electrocatalysts remains unclear. We directly measure, for the first time, the interface carrier transport properties of a prototypical visible-light-absorbing semiconductor, α-Fe2O3, in contact with one of the fastest known water oxidati...
متن کاملIncorporation of 12-Tungstophosphoric acid in Titania spheres and fabrication of core-shell Polyoxotungstate/Titania nanostructures
Core-shell 12-tungstophosphoric acid/TiO2 (HPW/TiO2) nanoparticles at 10 and 20% of HPW have been synthesized by simple in-situ sol- gel method. Characterization of the samples was carried out by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared (FTIR). The X-ray diffraction patterns of as prepared solid samples, indicated characterist...
متن کاملToxicological Characterization of Phthalic Acid
There has been growing concern about the toxicity of phthalate esters. Phthalate esters are being used widely for the production of perfume, nail varnish, hairsprays and other personal/cosmetic uses. Recently, exposure to phthalates has been assessed by analyzing urine for their metabolites. The parent phthalate is rapidly metabolized to its monoester (the active metabolite) and also glucuronid...
