Zirconium doped MCM-41 supported WO3 solid acid catalysts for the esterification of oleic acid with methanol

Study of the esterification reaction of acetic acid with n -butanol over supported WO 3 catalysts

“…Indeed, in the last decade, a high number of studies showed that tungsta [2][3][4][5][6][7][8][9], molybdena [10][11][12], vanadia [13,14] and niobia [15] supported on appropriate supports were effective catalysts for the esterification reaction, one of the fundamental acid-catalyzed reactions.…”

Enhancing tungsten oxide/SBA-15 catalysts for hydrolysis of cellobiose through doping ZrO2

“…4 [29,31,39]. For W 30 Zr 3 /SBA-15, the intensity of these bands decreased significantly (trace b).…”

“…Cheng et al [30] introduced a mixture of W/Zr oxides on various porous silica materials by co-impregnation and applied these catalysts in n-pentane isomerization. Jiménez-López et al [31] prepared a series of catalysts by supporting WO 3 on Zr-doped MCM-41 using impregnation and used the catalysts for the esterification of oleic acid with methanol. Recently, Yi and co-workers [32] synthesized Zr-WO x modified mesoporous SiO 2 catalysts using a refined hydrothermal method for esterification of 1-butanol with acetic acid, which exhibited much higher activity than HZSM-5 and conventional WO 3 /ZrO 2 catalysts.…”

Modification Effects of B2O3 on The Structure and Catalytic Activity of WO3-UiO-66 Catalyst

“…Then, mesoporous silicas, such as MCM-41 and SBA-15, were introduced into the system of tungsten oxide-zirconia catalyst. Jiménez-López et al synthesized a series of Zr-doped MCM-41 supported WO 3 catalysts by the impregnation method and studied their catalytic performance for the esterification of oleic acid with methanol [14]. Ge and coworkers prepared a high surface area WZr/SBA-15 catalyst by the hydrothermal method for the hydrolysis of cellobiose, with significantly higher activity than a conventional WO 3 /ZrO 2 catalyst that was prepared by the impregnation method [15].…”
