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

This is a novel way to generate hydrogen from pure water by converting mech anical energy to chemical energy. The phenomenological aspects of the mecha no-catalytic overall water-splitting are reviewed, and the basic feature of the catalytic process is clearly established. The estimation of the conver sion from mechanical to chemical energy is also shown. Experimental results . carried out to reveal the mechanism of the mechano-catalytic reaction are described.
