The catalytic behaviors of lanthanum and neodymium oxides for dehydrogenation/dehydration of ethanol (Texas A&M University. Libraries, 1985)The ethanol dehydrogenation and dehydration reactions have been employed to investigate the nature and behavior of catalytically active sites on lanthanum and neodymium sesquioxides. In support of this objective, x-ray ...

(Texas A&M University. Libraries, 1982)The natures of adsorption sites on La(,2)O(,3), Nd(,2)O(,3), and selected praseodymium oxides were investigated by examining surface reactions of probe molecules using computerized transmission infrared (IR) spectroscopy ...

(Texas A&M University. Libraries, 1977)Infrared spectroscopy was used to examine the surface properties of catalytic La₂Og₃ and a 1:1 mixture of LaOCl + La₂Og₃. Spectral studies of the dehydration/rehydration of the La(OH)₃/La₂O₃ system revealed the existence ...
