MoO2 229.5 eV MoO3 233.1 eV Experimental information S2s region strongly overlaps Mo3d when sulfur is present as sulfate. Interpretation of XPS spectra Mo3d peaks are asymmetric for molybdenum metal. Peaks are symmetric for Mo oxides. Mo3d region has well separated spin-orbit c...
本文应用XPS法测定了MoO_3/TiO_2,MoO_3/γ-Al_2O_3和MoO_3/SiO_2等体系的I_(Mo3d)/I_(Ti2p),I_(Mo3d)/I_(Al2p),I_(Mo3d)/I_(Si2p)随MoO_3加入量(g/g载体)递变的关系。测定结果表明MoO_3在这几种载体上都有一分散阈值,阈值前MoO_3在载体上呈单层分散,阈值后剩余的MoO_3以晶粒形式分...
Interpretation of XPS spectra Mo3d peaks are asymmetric for molybdenum metal. Peaks are symmetric for Mo oxides. Mo3d region has well separated spin-orbit components (Δ=3.15eV). General comments Multiple oxides observed (MoO, MoO2, MoO3). Argon sputtering reduces oxides ...
MoO3 and Mo2C have emerged as remarkable catalysts for the selective hydrodeoxygenation (HDO) of a wide range of oxygenates at low temperatures (that is, ≤673 K) and H2 pressures (that is, ≤1 bar). Although both catalysts can selectively cleave C
