Reduction of Cobalt and Iron Corroles and Catalyzed Reduction of CO 2

May 1, 2002
Author(s)
J Grodkowski, Pedatsur Neta, E Fujita, A Mahammed, L Simkhovich, Z Gross
The role of cobalt and iron corroles in catalytic CO 2 reduction has been studied. Chemical, electrochemical, and photochemical reductions of the stable metal corroles Ph 3PCo III(tpfc) (tpfc = 5,10,15-tris(pentafluorophenyl)corrole), ClFe^IV^(tpfc), and

Reaction Kinetics in Ionic Liquids as Studied by Pulse Radiolysis: Redox Reactions in the Solvents Methyltributylammonium Bis(trifluoroniethyl-sulfonyl)imide and N-Butylpyridinium Tetrafluoroborate

April 1, 2002
Author(s)
D Behar, Pedatsur Neta, C R. Schultheisz
Rate constants for several reduction and oxidation reactions were determined by pulse radiolysis in three ionic liquids and compared with rate constants in other solvents. Radiolysis of the ionic liquids methyltributylammonium bis(trifluoromethylsulfonyl

Copper-Catalyzed Radiolytic Reduction of CO 2 to CO in Aqueous Solutions

May 1, 2001
Author(s)
J Grodkowski, Pedatsur Neta
Radiolysis of aqueous solutions containing CO 2 and Cu(II) ions under reducing conditions leads first to reduction of the Cu(II) and then to formation of CO. Experiments under various conditions show that although Cu(II) was often reduced to colloidal Cu(0

Manganese(III) Biliverdin IX Dimethyl Ester: A Powerful Catalytic Scavenger of Superoxide Employing the Mn(III)/Mn(IV) Redox Couple

February 1, 2001
Author(s)
I Spasojevic, I Batinic-Haberle, R D. Stevens, P Hambright, A N. Thorpe, J Grodkowski, Pedatsur Neta, I Fridovich
A manganese(III) complex of biliverdin IX dimethyl ester, Mn IIIBVDME} 2 was prepared and characterized by elemental analysis, uv/vis spectroscopy, cyclic voltammetry, chronocoulometry, electrospray mass spectrometry, freezing-point depression, magnetic

Reduction of Cobalt and Iron Phthalocyanines and the Role of the Reduced Species in Catalyzed Photoreduction of CO 2

December 1, 2000
Author(s)
J Grodkowski, T Dhanasekaran, Pedatsur Neta, P Hambright, Bruce S. Brunschwig, K Shinozaki, E Fujita
The role of cobalt and iron phthalocyanines in catalytic CO 2 reduction has been studied. Chemical, photochemical, and radiolytic reductions of the metal phthalocyanines (Pc) have been carried out in organic solvents, and reduction of their tetrasulfonated

Cobalt-Corrin Catalyzed Photoreduction of CO 2

March 1, 2000
Author(s)
J Grodkowski, Pedatsur Neta
A first attempt to use cobalt corrins (B 12) as homogeneous catalysts for photoreduction of CO 2 to CO and formic acid demonstrates that the corrins act as catalysts for this process and that they are much more efficient than cobalt porphyrins.
