Photoelectrochemical reduction of nitrite ions to ammonia on CdS photocatalysts

The photoelectrochemical reduction of nitrite ions to ammonia on US photocatalysts was investigated in the slurry mode. The oxidation and the reduction reactions take place separately, thus, decreasing the electron-hole recombination and enhancing the yield of ammonia. (C) 2003 Elsevier Science B.V.
