A novel supported-catalyst SiO₂-TPACo of covalently anchoring a [Co(TPA)Cl]Cl moiety onto SiO₂ nanoparticles (NP) was prepared and characterized. The SiO₂-TPACo exhibits robust dual activity of mediating CO₂ and protons reduction to CO and H₂, respectively, in a noble-metal-free photochemical system; the CO/H₂ ratio satisfies requirement of syngas.
