V-substituted polymolybdenum phosphoric acid (PV_xMo) supported on mesoporous silica was prepared and investigated as a catalyst for the oxidation of glycerol to formic acid in a batch operation. Different synthetic methods for PV_xMo supported on mesoporous silica were compared. Detailed characterizations of the final products were carried out by N₂ adsorption and desorption, XRD, HR-TEM, SEM, ICP-OES, XANES, NH₃-TPD, and FTIR to identify the chemical properties and the porous structure of silica-supported PV_xMo, as well as the strong interactions between PV_xMo with the silica skeleton. These critical properties explain the bifunctionality of silica-supported PV_xMo as a catalyst for the selective oxidation of glycerol to formic acid with standing stability.

制备了介孔二氧化硅上负载的V取代的多钼磷酸（PV _x Mo），并作为批处理操作中的甘油氧化为甲酸的催化剂进行了研究。比较了介孔二氧化硅负载的PV _x Mo的不同合成方法。通过N ₂吸附和解吸，XRD，HR-TEM，SEM，ICP-OES，XANES，NH ₃ -TPD和FTIR对最终产物进行详细表征，以鉴定二氧化硅负载的化学性质和多孔结构PV _x Mo，以及PV _x Mo与二氧化硅骨架之间的强相互作用。这些关键特性解释了二氧化硅负载的PV _x的双功能性Mo作为催化剂，可以稳定地将甘油选择性氧化为甲酸。
