Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A robust, safe and magnetically recoverable palladium catalyst was synthesized by anchoring Pd(II) onto ethylenediaminetetraacetic acid‐coated Fe<sub>3</sub>O<sub>4</sub> (Fe<sub>3</sub>O<sub>4</sub>@EDTA) magnetic nanoparticles. The Fe<sub>3</sub>O<sub>4</sub> magnetic nanoparticle‐supported Pd(II)–EDTA complex catalyst thus obtained was characterized using scanning and transmission electron microscopies, thermogravimetric analysis, vibrating sample magnetometry, X‐ray diffraction, and <named-content content-type="chemicalTechnology" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">inductively coupled plasma</named-content> atomic emission and Fourier transform infrared spectroscopies. Fe<sub>3</sub>O<sub>4</sub>@EDTA–Pd(II) was screened for the <named-content content-type="reactionType" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">Suzuki reaction</named-content> and <named-content content-type="reactionType" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">reduction of nitro compounds</named-content> in water. The Pd content of the catalyst was measured to be 0.28 mmol Pd g<sup>−1</sup>. In addition, the Fe<sub>3</sub>O<sub>4</sub>@EDTA–Pd catalyst can be easily separated and recovered with an external permanent magnet. The anchored solid catalyst can be recycled efficiently and reused five times with only a very slight loss of <named-content content-type="chemicalTechnology" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">catalytic activity</named-content>.
