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
