Palladium nanoparticles supported on MnFe2O4/SiO2/TT as highly active and reusable catalysts for the reduction of nitroarenes and oxidation of sulfide

In this work, the TT-Pd complex immobilized onto the surface of MnFe₂O₄/SiO₂ magnetic nanoparticles was successfully prepared via a simple and inexpensive procedure. The prepared nanocatalyst was considered a robust and clean nanoreactor catalyst for the nitroarene and oxidation of sulfides under green conditions. This eco-friendly heterogeneous catalyst was characterized by Fourier transform infrared spectroscopy, X‐ray diffractometry, energy‐dispersive X‐ray spectroscopy, inductively coupled plasma‐atomic emission spectroscopy, thermogravimetric analysis, vibrating sample magnetometry, X-ray Photoelectron Spectroscopy, and scanning electron microscopy techniques. The use of green medium, easy separation, excellent reusability of the nanocatalyst, and short reaction time are some outstanding advantages of this method.

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
