摘要: Abstract The stability effect of Mn dopand on the potassium loss from β -ferrite, active phase a styrene catalyst, has been quantified for first time in succinct measurements by means species-resolved (K and K + ) thermal alkali desorption technique. Upon introduction 2 wt% energies increased 1.06 eV ions, whereas atomic barrier, which is crucial volatilization, was enhanced 1.52 eV. As result, both fluxes are significantly extinguished.
