Retainment of mesoporous nature after incorporation of WO3 during the preparation of SBA-16. Doping WO3 into SBA-16 increases the acidity. Among the catalysts, 3 wt% WO3-SBA-16 is optimum for levulinic acid esterification. 3 wt% WO3-SBA-16 catalyst exhibits steady activity during time on stream operation for 10 cycles.
