Bio‐MOF‐11 Derived Amorphous Cobalt Hollow Nanospheres to Access Bioactive Quinazolinone Scaffolds and Aromatic Amines

Amorphous cobalt hollow nanospheres, with high concentration of surficial active sites and Co–N sites, are derived from pyrolising cobalt adeninate metal−organic framework, Bio‐MOF‐11, to access bioactive quinazolinone scaffolds and aromatic amines. Modulated electron states of the amorphous cobalt and the high‐density Co–N active sites enhance the intrinsic catalytic activity.
