In situ confinement of ultra-small metal nanoparticles in redox-active zirconium MOFs for catalysis†
Abstract
Herein, we successfully fabricated ultra-small metal nanoparticles into two stable Zr-based metal–organic frameworks via in situ redox reactions between triphenylamine and the corresponding metal ions to afford Pd NPs@1 and Pd NPs@2, which exhibit excellent activity and reusability for Suzuki coupling reactions as heterogeneous catalysts.
