Abstract
The Yolk-Shell nanoreactors, characterized by a void region separating the core from the shell, are recognized as superior heterogeneous catalysts because of their enhanced mass transport capacity, robust stability, and remarkable catalytic performance. A hollow Yolk-Shell nanoreactor involving, CuFe2O4 magentic nanoparticles (MNPs) as the Yolk and mesoporous polymelamine formaldehyde (m-PMF) was prepared as the shell, together with palladium nanoparticles (NPs) stabilized on the surface of CuFe2O4 MNPs and encapsulated in the void space. Its structure was fully characterized using different analyses, obtained from Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), X‐ray diffraction (XRD), N2 Adsorption–Desorption, transmission electron microscopies (TEM), and vibrating sample magnetometry (VSM) techniques. The permeable and durable m-PMF shell that encased the Pd NPs facilitated the reaction within the empty cavity. Following this, the Yolk-Shell CuFe2O4@Pd@HM-PMF nanoreactor, known for its hollow structure, was evaluated as a proficient catalyst in the Mizoroki–Heck coupling reaction. Additionally, it demonstrated magnetic separability and exhibited satisfactory recyclability.
