摘要成功制备了β-硅钼酸(SMA)/ sio2，并对其甲醇部分氧化催化活性进行了研究。经过催化研究，在反应前预处理后，β-SMA转化为另外两种具有不同拉曼相对峰比的α- moo3。另一方面，还制备了α-SMA/ sio2进行比较。α-SMA被分解为表面氧钼酸盐，有利于cox的形成，而β-SMA形成moo3，促进HCHO的形成。图形抽象。
Abstractβ-silicomolybdic acid (SMA)/SiO2was successfully prepared and its catalytic activity in methanol partial oxidation was studied. After catalytic study, β-SMA was transformed into two other types of α-MoO3that had different Raman relative peaks ratios upon the pre-treatment prior to the reaction. On the other hand, α-SMA/SiO2was also prepared for comparison. α-SMA was decomposed into surface oxomolybdates species which favored the formation of COxwhile MoO3was formed from β-SMA and promoted HCHO formation.Graphical Abstract.
