Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Nobel metal nanoparticle loaded carbon nanotube (CNT) composites have wide applications in heterogeneous catalysis, and the catalytic properties are largely controlled by the size, composition, and dispersion state of the noble metal nanoparticles. However, the chemically inert feature of CNTs makes it difficult to directly disperse noble metal nanoparticles in a uniform manner. In this work, by an in situ galvanic replacement reaction between Cu nanoparticles and noble metal ions, a simple and efficient strategy was developed to produce magnetic multiwalled (MW) CNTs–Fe₃O₄ supported noble metal nanoparticles. The MWCNTs–Fe₃O₄–Pd showed impressive activity in the carbonylative Sonogashira coupling reaction and in the catalytic hydrodegradation of methylene blue.</p> </abstract>
