dc.description | In this work we obtained materials of titanium dioxidewhit mixed oxide CoO-TiO2 and WO3-TiO2(1.0, 3.0, 5.0 %wt). The solids were characterizedby; nitrogen physisorption (BET) and porosity(BJH), XRD patterns and UV-Vis spectroscopy.The photoactivity was evaluated using a Pyrexreactor of 200 ml using a solution ethanol-water(1:1 molar ratio) and 0.1 g of catalyst using a highpressure Hg lamp (with a wavelength of 254 nmand an intensity of 2.2 mW/cm2 encapsulated ina quartz tube. The results showed materials withspecific surface area among 89 to 95 m2/g and 41to 91 m2/g with mesopority characteristics. TheXRD patterns show the formation of the crystallineanatase phase. The band gap energy (Eg) for thematerials were obtained with UV-Vis spectroscopy,the Eg values were lower than 3.2 eV for both mixedoxide. In the water splitting evaluation a maximin the efficient was found at Co and W at 5 wt.%.The hydrogen produced was 1000 μmol/h and 950μmol/h respectively, this is a value comparable torespect other works. | en-US |
