Abstract
A well-designed magnetic rodlike MOF-based nanocomposite confining highly dispersed Pt single atoms and clusters (denoted as Fe3O4-NR@ZIF-8/Pt) is fabricated and plays dual functional roles in high-efficient nanocatalysis and magnetically actuated stirring. Results of the catalytic experiments for dye degradation, hydrogen production of NaBH4, and hydrogenation of olefins show that Fe3O4-NR@ZIF-8/Pt exhibits enhanced catalytic performance in the absence of external stirring, compared with those of traditional catalytic systems, which need external stirring. Of special note, this proposed structure provides a facile and effective methodology to improve the catalytic performance of MOF-based composites without traditional external stirring and offers an outlook toward extending more application fields of MOFs and other porous materials.
