The carbonate complex 10 (Figure ), formed from activated complex 1 and captured atmospheric CO₂, can generate formaldehyde (complex 12) and/or methanol (complex 13) through a hydrogenation mechanism. Hydrogen is produced internally via photocatalytic water splitting . The continuous catalytic cycle shown in Figure , incorporating DAC of CO₂, provides a sustainable source of formaldehyde and methanol as valuable feedstocks.
