ELECTROCHEMICAL FIXATION OF MOLECULAR NITROGEN ON p-TYPE GALLIUM PHOSPHIDE PHOTOCATHODE.

Abstract

Electrochemical fixation of molecular nitrogen to ammonia and hydrazine at p-type GaP photocathodes was studied in nonaqueous electrolytes containing either one of titanium tetraisopropoxide, titanium trichloride, vanadium trichloride, or chromium trichloride and a trace amount of water. Positive evidences for the nitrogen fixation were obtained in these electrolytes, but the current efficiency was quite low, and usually less than 1%. It is suggested from this study that there are a variety of choices of electrolyte systems for the nitrogen fixation.
