Present work demonstrated a convenient method for the synthesis of flower shaped tungsten supported TiO2/SiO2 (W/ Ti/SiO2) without using templates by sol-gel method in a single step. The prepared W/Ti/SiO2 has been employed as heterogeneous catalyst for the transesterification of variety of feed stocks viz., fresh cotton seed, waste cotton seed and karanja oil with methanol. The surface morphology and shape of prepared catalyst was determined by field emission scanning electron microscopy (FESEM) and high resolution transmission electron microscopy (HRTEM) studies. The catalyst structure and crystallite size were determined by the by powder X-Ray Diffraction (XRD) study. The catalyst active sites were quantified by NH3 temperature programmed desorption (TPD) study and surface area of prepared catalysts was determined by Brunauer- Emmett-Teller (BET) technique. Under optimal reaction conditions of methanol/oil molar ratio of 30:1, catalyst to oil weight fraction of 5 % and 65�?° C reaction temperature, a 98% fatty acid methyl esters (FAMEs) yield was obtained from the waste cotton seed oil in 4 hour. The optimized catalyst was reused successfully for transesterification reaction up to 5 cycles without any significant loss in activity. Few physicochemical properties of the prepared biodiesel sample have also been studied and compared with standard values.
