Abstract

Simultaneous reduction of carbon dioxide and nitrite ions was investigatedat gas-diffusion electrodes with various metallophthalocyanine (M-Pe, M: Cr, Mo, Mn, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, In, TI, Sn and Pb) catalysts. The formation of urea, CO, formic acid and ammonia at the gas-diffusion electrodes with Group 8-14 catalysts, except for Al and Ge, was found in the simultaneous reduction. The maximum current efficiency of ureaformation is about 40% at - 1.5 V on Ni-Pc catalysts. The formation of urea at the gas-diffusion electrodes with Group 4-7 catalysts was not found inthe simultaneous reduction of CO2 and nitrite. The ability for urea formation with the catalysts depends on the ability for CO and NH, formation. Thecatalysts with high ability for CO and NH, formation could form large amounts of CO-like and ammonia-like precursors. (C) 2001 Elsevier Science B.V. All rights reserved.
