Deconvolution methods doublet

The nitrogen content of the molybdenum nitride hydrodesulfurization catalysts was determined by x-ray phoioeleciron spectroscopy. The Mo 3d spectra were fitted into six sets of Mo doublets (Mo 3dv and 3ds ) with each fwhm corresponding to six different molybdenum species. The XPS N Is peak in the catalysts was deconvoluted with the individual Mo 3pt 2 signals based on the same distribution of the Mo 3d electrons of Mo 3p3 2 as the Mo 3d. 2 spectra. This method is accurate for the determination of the N/Mo ratio in molybdenum nitrides with a small error during hydrotlesulfurization reaction.
