A pyrene-appended iron triphenyl porphyrin bearing six pendant OH groups on the phenyl rings in all ortho and ortho′ positions was immobilized on carbon nanotubes via noncovalent interactions and further deposited on glassy carbon. X-ray photoelectron spectroscopy and electrochemistry confirm catalyst immobilization. Using the carbon material, highly selective and rapid catalysis of the reduction of CO 2 into CO occurs in water (pH 7.3) with 480 mV overpote...

Ease of separation of CH 3 OH is demonstrated by simple distillation from the reaction mixture. The robustness of the catalytic system was shown by recycling the catalyst over five runs without signif...

Journal of the American Chemical Society by Yusuke Masuda, Naoki Ishida and Masahiro Murakami  /  1d  //  keep unread  //  hide  //  preview C–C bond forming carboxylation reactions of organic molecules with carbon dioxide (CO 2 ) have gained considerable attention in organic synthesis. (1) Most conventional methods including Grignard reactions and transition metal catalysis use stoichiometric amounts of reducing agents or bases. (2-4) The major driving force of these carboxylation reactions derives from the chemical reagents. Alternatively, electro- (5) or photo-assisted (6) reductive carboxylation reactions have been devised. Electron donors like triethylamine were used as the sacrificial reducing agents in most cases. Herein, we report a unique and clean carboxylation reaction that uses no sacrificial reagent but light energy as the driving force; simply upon UV irradiation of a DMSO solution of o -alkylphenyl ...

Here we report modular optimization of covalent organic frameworks (COFs), in which the building units are cobalt porphyrin catalysts linked by organic struts through imine bonds, to prepare a catalytic material for aqueous electrochemical reduction of CO 2 to CO. The catalysts exhibit high Faradaic efficiency (90%) and turnover numbers (up to 290,000, with initial turnover frequency of 9400 h...
