Magnetically recyclable core–shell nanocatalysts for efficient heterogeneous oxidation of alcohols

Abstract

We describe the designed fabrication of magnetically recyclable core–shell Pd nanocatalysts for the efficient oxidation of alcohols under base-free reaction conditions in water.

Magnetically separable γ-Fe2O3 nanoparticles: An efficient catalyst for acylation of alcohols, phenols, and amines using sonication energy under solvent free condition

“…The magnetic separable nanoparticles have advantages such as insoluble in reaction mixture, paramagnetic nature, and easy separation of nanocatalyst by using magnet which avoids the catalyst filtration; it prevents the aggregation of nanocatalyst which increases the durability of the catalysts, recycling and reusability of catalyst [32]. The researchers paid their efforts to synthesis of magnetic s magnetic separable nanoparticles and their applications in catalysis [33][34][35]. In our recent work, we have developed several facile and greener synthetic routes for nanoparticles and developed their applications in catalysis [36][37][38][39][40].…”

Magnetically Separable and Sustainable Nanostructured Catalysts for Heterogeneous Reduction of Nitroaromatics

“…Schematic preparation of the magnetically-recyclable core-shell nanocatalysts. Reprinted with permission from [69].…”

“…The magnetic core could be readily utilized for the easy recovery and recycling of the nanocatalysts. To prepare highly stable and practically effective core-shell catalysts, Shokouhimehr et al designed and synthesized a magnetically-recyclable core-shell with the robustly fixed Pd nanocatalysts on a polymer layer for the efficient oxidation of alcohols, Suzuki cross-coupling and reduction of nitroaromatics [69]. The Pd NPs half partitioned in the polymer matrix could provide not only high catalytic activity, but also stabilization of the nanocatalysts under harsh reaction conditions.…”
