ABSTRACT:
Nitric oxide, an odd-electron molecule, has been found to react with m-phosphoric acid to displace hydrogen and form nitrosyl m-phosphate. The addition of water to the nitrosyl salt regenerates the m-phosphoric acid, half the nitric oxide and the other half as nitrogen dioxide which can then be converted to nitric oxide in an oxidation process. These reactions thus form a cyclic process for obtaining hydrogen from water with low level energy.
