Oxygen vacancyThermally activated functionalized-MOFsDensity functional theory (DFT)Investigating an feasible catalytic mechanism on Zn-MOF and its derivative amphoteric oxides is of great importance for esterification. Herein, activated Fe3O4-functionalized IRMOF-1 that was well retained the porosity was ...
Oxygen vacanciesDielectric propertiesPolarizationDeficiencyThere is an urgent need for dielectrics to suit multitudinous burgeoning applications with high-temperature dielectric stability. Here the intrinsic defect and polarization mechanism are investigated in A-site-deficient 0.66(Bi0.5Na0.5)TiO3-0.06BaTiO3-...
Off-stoichiometry of perovskite structural Bi0.5Na0.5TiO3(BNT)ferroelectrics can give rise to considerable oxide-ion conductivity.The inherent structural characteristics are urgent to be resolved due to its particular sensitivity of the conduction mechanism to the nominal composition and synthesis process....
Because Ce doping into the skeleton of LaFeO3 could cause the change of iron valence state as well as the change of the reactive oxygen species and oxygen vacancies of the catalyst. Three ways of O-2 involved in this reaction were considered, a synergistic mechanism of oxygen vacancies, the...
We present the theoretical DFT/B3LYP investigations on the cluster nucleation process and moving mechanism for the Ptn (n = 1, 2, 3, 4, 8, and 12) clusters deposited on MgO surface with an embedded cluster model. The structures and energies of the Ptn clusters adsorbed on the perfect and...
Tuning the oxygen activity in perovskite oxides (ABO) is promising to surmount the trade-off between activity and selectivity in redox reactions. However, this remains challenging due to the limited understanding in its activation mechanism. Herein, we propose the discovery that generating subsurface ...
As confirmed by the XPS, PL, Raman and I – V results, the oxygen vacancies and electron concentrations were the dominating effects and an oxygen vacancy mediated NO 2 sensing mechanism was presented and discussed.ZouChangweiEBSCO_AspApplied Surface Science...
