SrCl2-Promoted REOx (RE=Ce, Pr, Tb) Catalysts for the Selective Oxidation of Ethane: A Study on Performance and Defect Structures for Ethene Formation

Effects of Modifying Acidity and Reducibility on the Activity of NaY Zeolite in the Oxidative Dehydrogenation of n-Octane

“…The best conversions and selectivities were reported when these metals were promoted by alkaline earth metals such as Sr and Ba. Using rare earth metals containing catalysts in ODH generally improved activity and reduced deep oxidation [14][15][16].So far, the most studied catalysts are the transition metal oxide-based catalysts, with vanadium or molybdenum being the most studied active components. Such catalysts are employed in ODH, with common supports such as Al 2 O 3 , TiO 2 , ZrO 2 , MgO, and SiO 2 .…”

The effect of MgO doping on the structure and photoluminescence of YAG:Tb phosphor

“…The binding energy can be changed due to element kind, ionic valence, the electron layer state and the crystal structure. Even with the same elements, the shift or new peaks forming will be influenced just by the difference of valence or crystal structure [17][18][19][20]. It can be supposed that the forming of a little Tb 4+ in YAG:(Tb, Mg) phosphors happens easily after a prolonged soaking time or oxidizing annealing operation.…”

Microwave Hydrothermal Synthesis of Terbium Ions Complexed with Porous Graphene for Effective Absorbent for Organic Dye

“…Through the Tb 4d core level spectrum shown in Fig. 2 d, two regions were observed in this system suggesting the existence of different valence states [ 28 , 29 ]. The 168.4 eV peak would be related to Tb 4+ in Tb(III,IV) oxide, differing from Tb 4 O 7 and Tb 2 O 3 .…”
