Palladium Nanocatalysts Confined in Mesoporous Silica for Heterogeneous Reduction of Nitroaromatics

Magnetically Separable and Sustainable Nanostructured Catalysts for Heterogeneous Reduction of Nitroaromatics

“…Moreover, the comparison between the Ni@Pd/KCC-1 nanocatalysts and Ni@Pd NPs obviously showed that the Ni@Pd/KCC-1 nanocatalysts, with the easy accessibility of the active sites, exhibited higher catalytic activity than the unsupported Ni@Pd NPs. The well-dispersed nanocatalysts on mesoporous nanospheres are more stable than unsupported nanocatalysts, providing a green and environmentally benign protocol [53]. In addition, the Ni@Pd/KCC-1 nanocatalysts could be easily recovered from the reaction mixture under an external magnetic field.…”

Selective Hydrogenation of Cinnamaldehyde Catalyzed by ZnO-Fe2O3 Mixed Oxide Supported Gold Nanocatalysts

“…Most research work on noble metal nanocatalysts, especially for gold nanocatalyst, has been focused on oxidation reactions [9,10], and more extensive studies on highly efficient hydrogenations are required [11][12][13][14][15]. In the selective hydrogenation of unsaturated α,β-aldehydes, gold nanocatalysts have shown high selectivity toward the C=O group hydrogenation to the unsaturated alcohol, while other noble metals like Pd and Pt often present intrinsic selectivity toward C=C bond hydrogenation to saturated aldehyde [16].…”

The Isomerization of Limonene over the Ti-SBA-15 Catalyst—The Influence of Reaction Time, Temperature, and Catalyst Content

“…Mesoporous silica catalysts can be obtained in soft-templating processes, in which self-assembly of organic molecules (surfactants and block copolymers) is used to create pores of controlled sizes. This procedure forms an inorganic network around the templates via a sol-gel process [26][27][28][29][30].…”
