    Pd nanocrystals encapsulated in MOF-derived Ni/N-doped hollow carbon nanosheets for efficient thermal CO oxidation: unveiling the effect of porosity حسب Ipadeola, Adewale K.

    منشور في 2023
    "…The obtained Pd/Ni-MOF-HNC possesses hollow carbon sheets with a great surface area (153.05 m2 g−1), pore volume (0.12 cm3 g−1), rich Pd/Ni-Nx active sites, Ni-metal defects, rich N-content (7.53 at%), mixed Pd/Ni-oxide phases, and uniformly distributed ultra-small Pd nanocrystals (7.03 ± 1.10 nm); meanwhile, Pd/Ni-MOF-NC formed without etching had no porosity and less Ni-metal defects. …"
