Palladium nanoparticles supported on SiO2@Fe3O4@m-MnO2 mesoporous microspheres as a highly efficient and recyclable catalyst for hydrodechlorination of 2,4-dichlorophenol and reduction of nitroaromatic compounds and organic dyes

In this paper, we successfully prepared magnetic SiO2@Fe3O4@m-MnO2 microspheres with uniform morphology and mesoporous MnO2 shell. The prepared material was used as a catalyst support for fabricating the Pd(6%)/SiO2@Fe3O4@m-MnO2 nanocatalyst which exhibited excellent catalytic activity and easy recyclability in the environmental catalysis.
