Abstract

Bipyridine-containing covalent triazine framework (CTF-Bpy) was used to prove that the single site distribution of Co²⁺ was possible. The Co²⁺-loaded CTF-Bpy-Co produced 120 μmol CO with a selectivity of 83.8% over 10 h of irradiation (>420 nm). This work highlights the promising potential of single metal sites loaded with CTFs for photocatalytic CO₂ reduction.
