Hydrogen Production by Mechano-catalytic Water Splitting

1 Hydrogen Production by Mechano-catalytic Water Splitting 

In 1998 Domen and co-workers reported evolution of hydrogen and oxygen from distilled water when certain oxide powders were 

A hydrogen evolution rate of about 35 pmol/hr over the first few hours of reaction using NiO powder was reported. This decreased with time reaching a value of 20 pmol/h after 55 hours. The energy efficiency was calculated using the equation [206] 

The protons move towards the bottom of the glass cell G where they combine with electrons to generate hydrogen gas. Another possibility is the transfer of electrons from the particle surfaces to water, so that hydrogen is evolved according to the reaction [218] 

OH combines with the positive charge at the stirring rod R to evolve oxygen. The reaction is
