Influence of ZrO2 modifier and Mo precursor on the state of active component in MoO3/Al2O3 catalysts
Get PDFThe effects of precursor and the method of support modification on the properties of supported metathesis catalysts for reaction of ethylene and trans-butene-2 into propylene are considered. The objects of the research are the catalyst comprising γ-Al2O3-supported molybdenum oxide as well as the modified alumina-based supports. The Mo precursors used is shown to significantly affect the state of the supported component. The distribution and morphology of the particles of active component inside the pores of the support differ for the ZrO2-modified samples prepared by impregnation and wet mixing methods
Interface features and electronic structure of Bi2SiO5/β-Bi2O3 hetero-junction
Get PDFAtomic and electronic structure of Bi2SiO5/β-Bi2O3 hetero-junction was described by means of density functional theory. The interface was found to be narrow-gap semiconductor with indirect band gap. The redistribution of states near the Fermi level in hybrid structure and the impact of spin-orbit coupling are discussed
