Análise por componentes principais de espectros nexafs na especiação do molibdênio em catalisadores de hidrotratamento
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 (LCA) allowed the detection and quantificati...
