金属离子改性交联粘土催化甲醇脱氢生成甲醛

Formaldehyde formation form methanol dehydrogenation catalyzed by metal ion- modified crosslinked clay

甲醇在硅交联云母-蒙脱土(Si-CLR)上发生脱氢反应生成甲醛,且催化活性较稳定。在不同金属离子交换的Si-CLR上,甲醛的吸附态及反应机理有所不同。并推测了金属离子改性的Si-CLR的活性中心。

Methanol is dehydrogenated over Si- CLR to form formaldehyde, and the catalytic activity is rather stable. Over the different metal ion- crosslinked Si-CLR, the adsorption state and the reaction mechanism are varied. The active center of metal ion-modified Si-CLR is also inferred.
