Activities of Phosphorus-Based Catalysts

IR Data Characterizing Selected Phosphorus-Based Catalysts after Drying and Calcination 

1180-1130 P-O (wavenumber decreases with decreasing bond order) P/alumina 77 

912-918 Weakly bound bridge bands in M0O4 tetrahedra Dried NiMoP/alumina 29 

At the outset, it is important to know whether a very small quantity of phosphorus leads to detectable changes in the catalytic performance. Led-oux et at. 123) reported that 120 ppm of phosphorus only slightly affects
