Abstract

Reduction of a series of known heteropoly acids with Keggin unit, H3PMo12-n WnO40(n = 0, 3, 6, 9, 11, 12) was studied by ESR. Reduction of these acids in hydrogen was investigated by ESR, and two signals were observed Substitution of Mo by W in the Keggin anion is suggested to affect the reduction mechanism.

Key words: PHOSPHORIC ACID P, OXIDATION REDUCTION REACTION, HETEROPOLYACID, ELECTRON SPIN RESONANCE SPECTROMETRY, TUNGSTIC ACID P, MOLYBDIC ACID
