The synthesized nanoparticles properties were compared after using methanol, ethanol, and propanol fuel sources. The synthesized TiO 2 were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), thermal analysis (thermogravimetric analysis, TGA, and differential scanning calorimetry, DSC), and surface area Brunauer-Emmett-Teller (BET) method. The photocatalytic activity of TiO 2 nanoparticles was investigated by measuring the degradation of methylene blue. It was found that methanol and ethanol burners can be used as an alternative furnace that can yield TiO 2 nanoparticles with physicochemical properties comparable to that of commercial TiO 2 nanoparticles, while a propanol burner cannot be used as an alternative fuel. © 2011 Chemical Society of Ethiopia.Mahidol UniversityChemistryArticleSCOPUS
