Shape-controlled nanostructured MoO3/CeO2 catalysts for selective cyclohexene epoxidation

Shape-Controlled MoO3/MnOx Nanocatalyst for the Selective Synthesis of 2-Phenylquinoxaline Drug Motifs

“…This reveals that the calcination temperature has shown a strong effect on the Mn–O bonds of Mn oxides, resulting in the variation of the peaks’ intensity. The Raman bands belonging to crystalline, tetrahedral, and oligomeric MoO x are not found in MoO 3 /MnO x materials. − This indicates that the MoO 3 species are highly dispersed on the MoO 3 /MnO x materials, confirming the XRD studies (Figure a).…”

“…Two types of oxygen species are present in all of the materials (Figure S4, Supporting Information). The peak at 529–520 eV corresponds to the lattice oxygen, and the peak at 531.5–532.9 eV represents the adsorbed oxygen species. − ,, …”

“…The peak at 529−520 eV corresponds to the lattice oxygen, and the peak at 531.5−532.9 eV represents the adsorbed oxygen species. [37][38][39]45,46 Both MnO x -5 and MoO 3 /MnO x materials exhibited type IV isotherms, with a considerable variation in the shape of the hysteresis loops (Figure 5a). The MoO 3 /MnO x -4 nanomaterial shows an H2-type hysteresis loop, revealing the presence of mesopores in these materials.…”

Review of Shape-Controlled CeO2 Nanocatalysts for Purification of Auto-Exhaust Pollutants

“…Besides the size of CeO 2 particles, the particles’ shape is an important parameter in optimizing the redox and surface properties for various catalytic applications. − The distinctive morphology of ceria can prevent the nanoparticles (NPs) from agglomeration and improve its catalytic stability for air pollution control. Thus, synthesizing ceria nanocrystals with well-defined morphologies is considered a promising structure-engineering strategy for developing advanced CeO 2 -based catalysts with improved properties.…”
