Summary: In this study, polyhydroxylated lignin was prepared by demethylation and hydroxylation of lignin, followed by grafting of phosphorus-containing groups through nucleophilic substitution reaction. The resulting material, PHL-CuI-OPR2, could be used as a carrier for the preparation of heterogeneous Cu-based catalysts. The optimal PHL-CuI-OPtBu2 catalyst was characterized and its catalytic performance in the Ullmann C-N coupling reaction was evaluated, showing high product yields. Furthermore, the catalyst could be easily recovered from the reaction medium.

Summary: Colloidal Ag particles decorated with Fe3O4 islands can be activated as inverse catalysts for C(sp(2))-H heteroarylation either electrochemically or photochemically. The silver-iron oxide (SIO) particles are reduced into redox-active forms by cathodic charging at mild potentials or short-term light exposure, and can be reused multiple times by magnetic cycling without further activation. The reduction peak shift is attributed to the overpotential produced by surface Fe3O4, which separates residual Ag ions or clusters from bulk silver. The catalytic efficiency of SIO is maintained even with acid degradation, and can be counteracted by simple addition of water to the reaction medium.

Summary: This study presents a facile in situ synthesis strategy for the production of MnFe2O4@PDA-Ag magnetically recyclable core-shell nanospheres with enhanced catalytic activity for the reduction of organic pollutants. The MnFe2O4@PDA-Ag nanocatalyst showed excellent recyclability, ease of magnetic separation, and high recovery ability with insignificant loss in catalytic efficiencies after several cyclic uses. The PDA coating on the surface of MnFe2O4 NPs allows for surface functionalization and the building of novel catalyst systems.

Summary: This work presents a facile green synthesis method for producing Fe3O4 magnetic nanoparticles (MNPs), which exhibit high catalytic activity in Fenton and photo-Fenton reduction reactions. The MNPs show spherical morphology and have an average diameter of 6.3 +/- 1.1 nm. The study demonstrates the superior efficiency of the MNPs in both processes at varied pH ranges. Additionally, the MNPs exhibit good reusability and can effectively reduce dye and Cr(VI) loads in water treatment processes.
