Pd Nanoparticles Immobilized on Orange-Like Magnetic Polymer-Supported Fe3O4/PPy Nanocomposites: A Novel and Highly Active Catalyst for Suzuki Reaction in Water

An orange-like catalyst of Pd nanoparticles supported by magnetic Fe3O4/polypyrrole nanocomposite is facilely prepared. It shows great activity for Suzuki coupling reactions in neat water under atmospheric pressure. This magnetic and water-soluble catalyst avoids the use of toxic solvents in traditional process of coupling reactions and can be easily recovered by mean of a convenient magnetic separation technique, demonstrating in both environmental friendliness and recyclability.Graphical Abstract

A series of nano/micro-sized metal–organic frameworks with tunable photoluminescence properties

Present studies on metal–organic frameworks (MOF) mainly focus on macro-scaled single crystals. However, the realization of MOF nanocrystals via a bottom-up one-step method still remains a significant challenge. Here, hierarchically assembled nanostructures of lanthanide-based MOFs with 1D and 3D morphologies have been successfully fabricated via a simple and rapid solution phase method at room temperature. Upon UV excitation, these nanomaterials exhibit highly efficient tunable luminescence properties, which come from the Eu3+ or Tb3+ ions. Moreover, white-light emission can be achieved by co-activating the organic ligand, Eu3+ and Tb3+ ions in the nano-MOFs.

Remarkable enhancement of Fe–V–Ox composite metal oxide to gold catalyst for CO oxidation in the simulated atmosphere of CO2 laser

A novel Au/Fe–V–Ox/Al2O3 catalyst displayed remarkable activity and good stability for CO oxidation in the simulated atmosphere of a CO2 laser with high CO2 levels up to 60 vol% and stoichiometric or even lower O2/CO ratio. The improved surface labile lattice oxygen on the FeOx and VOx modified Al2O3 plays a crucial role in its outstanding performance for the CO oxidation reaction in an oxygen-poor atmosphere.
