Análise por componentes principais de espectros nexafs na especiação do molibdênio em catalisadores de hidrotratamento Principal component analysis of nexafs spectra for molybdenum speciation in hydrotreating catalysts
<abstract language="eng">Bulk and supported molybdenum based catalysts, modified by nickel, phosphorous or tungsten were studied by NEXAFS spectroscopy at the Mo L III and L II edges. The techniques of principal component analysis (PCA) together with a linear combination analysis (LC...
