Mechano-catalytic overall water-splitting into hydrogen and oxygen on some metal oxides

This is a novel way to generate hydrogen from pure water by converting mechanical energy to chemical energy. The phenomenological aspects of the mechano-catalytic overall watersplitting are reviewed, and the basic feature of the catalytic process is clearly established. The estimation of the conversion from mechanical to chemical energy is also shown. Experimental results, carried out to reveal the mechanism of the mechano-catalytic reaction are described.
