An Anthracene‐Based Metal‐Organic Framework for Selective Photo‐Reduction of Carbon Dioxide to Formic Acid Coupled with Water Oxidation

Abstract

AZ r-based metal-organic framework has been synthesized and employed as ac atalystf or photochemical carbon dioxide reduction coupled with water oxidation. The catalysts hows significant carbon dioxide reduction property with concomitant water oxidation. The catalyst has broad visible light as well as UV light absorption property,w hich is furtherc onfirmed from electronic absorption spectroscopy. Formic acid was the only reduced product from carbondiox-ide with at urn-over frequency (TOF)o f0 .69 h À1 in addition to oxygen, which was produced with aT OF of 0.54 h À1 .N o externalp hotosensitizer is used and the ligand itself acts as the light harvester.T he efficient and selective photochemical carbond ioxide reductiont of ormic acid with concomitant watero xidation usingZ r-based MOF as catalyst is thus demonstrated here.

Rational Design of Metal–Organic Framework‐Based Materials for Photocatalytic CO2 Reduction

“…Organic linkers with high conjugation degrees can not only endow MOFs with reduced bandgaps but also favor the charge transfer process. [ 38 ] Su's group found broadband visible light absorption and efficient photogenerated charge generation in anthracene‐based Zr‐MOF (NNU‐28). [ 39 ] Furthermore, both the anthracene‐based organic linkers and Zr 6 oxo clusters could serve as the photocatalytic centers for visible light‐driven CO 2 reduction, affording a high formate formation rate of 183.3 μmol h −1 mmol MOF −1 .…”

Ionic Fe(iii)-porphyrin frameworks for the one-pot synthesis of cyclic carbonates from olefins and CO2

“…[15][16][17][18][19][20][21] In this direction, numerous strategies have been used for the utilization of CO 2 to obtain value-added chemicals. [22][23][24][25][26][27][28][29] Among them, production of cyclic carbonates by the functionalization of epoxides using CO 2 has gained special interest due to its absolute atom economy. [30][31][32][33][34][35] Notably, cyclic carbonates are of potential utility as precursors of polymeric materials, raw materials of pharmaceuticals and cosmetics, electrolytes in batteries, and so on.…”

Strategic Design of Mg-Centered Porphyrin Metal–Organic Framework for Efficient Visible Light-Promoted Fixation of CO2 under Ambient Conditions: Combined Experimental and Theoretical Investigation

“…The concentration of carbon dioxide in the atmosphere is increasing dramatically over the last two decades exceeding 400 ppm, currently . This significant increase in CO 2 levels in the atmosphere has been ascribed to a variety of human activities that result in greater fossil fuel consumption, resulting in major environmental issues. , In this regard, carbon capture and sequestration (CCS) has been adopted to combat increasing CO 2 levels. , However, owing to the energy-intensive nature of CCS, the application of an alternative and value-added option, that is, carbon capture and utilization (CCU), as a C1 resource for production of valuable chemicals and fuels has gained potential interest. − In this context, extensive research efforts are being made by researchers worldwide for the development of high-performance catalytic systems for effective utilization of CO 2 to prepare valuable compounds. − …”
