Enhanced photocatalytic CO2 reduction using a trimetallic organic framework as the catalyst under visible light

After adding Co, the photocatalytic CO reduction activity of Fe 0.02 Ni 0.10 –Co x –PCN-250 ( x = 0.05, 0.10, 0.15, 0.20 mol) was significantly higher than that of Fe 0.02 Co 0.10 –PCN-250 and Fe 0.02 Co 0.10 –PCN-250.
