Photoelectrochemical Reduction of p-Halonitrobenzenes
A detailed and comparative mechanistic study of the photoelectrochemical dehalogenation of the four p-halonitrobenzenes, X-C,H,-NO, (X = F, CI, Br, or I) in acetonitrile solution is reported. In the case of p-iodonitrobenzene, iodide loss is accomplished by electrochemical reduction alone. The formation of Iis shown to take place via an ECE process with the ultimate generation of the radical an...
متن کاملSemiconductor electrodes. 24. Behavior of photoelectrochemical cells based on p-type gallium arsenide in aqueous solutions
The electrochemical behavior of single-crystal p-type GaAs in aqueous solutions containing several redox couples (13-/1-, Fe(III)/Fe(II), Sn(IV)/Sn(II), Eu(III)/Eu(II)) in the dark and under irradiation is described. The observation that the difference in potential between that for the onset of photocurrent and the standard potential for the redox couple was 0.40.5 V, independent of the couple,...
متن کاملSemiconductor electrodes. 40. Photoassisted hydrogen evolution at poly(benzyl viologen)-coated p-type silicon electrodes
Poly(benzy1 viologen) (PBV) shows two reduction waves in aqueous (at -0.37 and -0.88 V vs. SSCE) or N,Ndimethylformamide (at -0.22 and -0.64 V vs. SSCE) solutions. A film of PBV on the surface of a p-type silicon electrode can be photoreduced at more positive potentials. When metallic Pt is incorporated into the film, the photoproduction of hydrogen occurs with an underpotential of ca. 0.4 V. T...
متن کاملEffects of Temperature and Particle Size Distribution on Barite Reduction by Carbon monoxide Gas
In this research, a mineral barite powder was reduced by carbon monoxide gas and the effects of reduction time and temperature was investigated as well as barite particle size. Results showed that the best result would be feasible when the barite particle sizes are between (-70 +100) in mesh scale. The barite reduction could reach the maximum level (98%) after reduction by carbon monoxide at 85...
متن کاملCarbon Monoxide Reduction of Iron Ore
C ERTAIN attention is paid today to the weaknesses of the classical blast furnace process, and interest is continuously increasing in methods for direct reduction without melting. Several different methods have been developed or suggested in the past, but so far only a few have been adopted for practical use. Another tendency in the iron industry of today is the change-over to concentrates, wit...
