The products were characterized by X-ray diffraction(XRD),thermogravimetry and differential scanning calorimetry(TG-DSC) analysis,scanning electron microscopy(SEM),transmission electron microscopy(TEM),energy dispersive X-ray spectroscopy(EDS) and selected-area electron diffraction(SAED). The results show that the nanowires are amorphous structures with diameters in the range of 100 to 150 nm.
This article deals with the influences of K2O on the acidity and MCH dehydrogenation stability of industry Pt-Sn/Al2O3 catalyst by pyridine-IR, adsorption and desorption of NH3 ,thermogravimetry(TG),DSC and MCH dehydrogenation.
