Cobalt Imidazolate Metal–Organic Frameworks Photosplit CO2 under Mild Reaction Conditions

Abstract: Metal-organic frameworks (MOFs) have shown great promise for CO 2 capture and storage. However, the operation of chemical redox functions of framework substances and organic CO 2 -trapping entities which are spatially linked together to catalyze CO 2 conversion has had much less attention. Reported herein is a cobalt-containing zeolitic imidazolate framework (Co-ZIF-9) which serves as a robust MOF cocatalyst to reduce CO 2 by cooperating with a ruthenium-based photosensitizer. The catalytic turnover number of … Show more

“…The Re complexes derivatized UiO-67 served as an active catalyst for photocatalytic CO 2 reduction to CO with a total turnover number (TON) of 10.9, which was three times higher than that of the homogeneous Re complexes [260]. Wang et al [262,263] demonstrated that a cobalt-containing zeolitic imidazolate framework (Co-ZIF-9) as a robust MOF co-catalyst could achieve the photocatalytic conversion of CO 2 to CO by using a Ru-based dye or CdS as the light harvester. It was suggested that the Co-ZIF-9 could not only promote the CO 2 capture and reduction catalysis, but also play a crucial role in improving electron transfers in the light harvester system [262,263].…”

Thus, it is naturally expected that MOFs as good supports can greatly promote the activity of a photocatalyst for CO 2 photoreduction to fuels due to their excellent adsorption capacity and photocatalytic reduction the activity for CO 2 .…”

“…ZIF-9 possesses a microporous crystalline structure with a composition of cobalt ions linked to benzimidazolate ligands [37]. We present a simple method for the fabrication of Co 3 O 4 /carbon nanofiber composite cathodes using ZIF-9 and carbon nanofiber precursors via electrospinning of a mixed solution comprising metallic cobalt and a carbonization-capable polymer (PAN).…”

“…Till date, several photocatalysts such as TiO2, inorganic metal complexes, metal oxide, metal sulphides, carbon-based composites etc. along with co-catalyst / photo sensitizers have been demonstrated for the photoreduction of CO2 under the light irradiation [9][10][11][12][13][14][15][16][17][18][19][20][21]. Band gap energy of semiconductors plays an important role to control the photocatalytic activity of nanomaterials and it should be in an appropriate range to absorb the visible light [22].…”
