The interfacial mechanism has always been a concern for 3-aminopropyltriethoxysilane (APTES)-grafted palygorskite (PAL). In this research, the of graft modification grafting APTES to surface PAL (100) was studied using density functional theory (DFT) calculation. results illustrated that different states influence inter- and intramolecular interactions between APTES/PAL (100), which are reflect...

A series of Fe–rich palygorskite supported manganese oxide (X%Mn–Pal) catalysts were prepared by co-precipitation method and used as for toluene oxidation. The components structure the as-prepared characterized XRD, Raman, TEM, XPS, in situ DRIFTS. results showed that 15%Mn–Pal catalyst exhibited highest catalytic activity (T90 = 227 °C) excellent cycling stability oxidation compared with other...
