The resulting catalysts were characterized by X-ray diffraction spectrometry, X-ray photoelectron spectroscopy, ultraviolet–visible diffuse reflectance spectroscopy, diffuse reflectance and transmittance infrared Fourier transform spectroscopy, energy dispersive X-ray scanning electron microscopy and differential pulse voltammetry. The generated titania are present in the form of anatase phase, without alteration of the zeolite framework. Homogeneous distribution of Ti is reached for up to 10 wt.% Ti, where higher contents seem to afford isolated conglomerates. The highest catalyst activity was reached with samples having 10 wt.% Ti. Catalyst activity was shown to be comparable to that exhibited by commercial P-25 after 1 h of UV light exposition. Experiments carried out in natural sunlight reached 92% decomposition of the methylene blue dye.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2013-10-14T13:25:59Z No. of bitstreams: 1 1-s2.0-S0926860X09000179-main.pdf: 1382827 bytes, checksum: c2fe35fcfd4ec9c8e5adef33d0b42b17 (MD5)Made available in DSpace on 2013-10-14T13:26:01Z (GMT).
