Stainless-Steel-Mediated Quantitative Hydrogen Generation from Water under Ball Milling Conditions

A robust and quantitative gaseous hydrogen generation method has been developed in an effort to achieve efficient H2 generation derived from H2O. The present reaction could be achieved by a simple ball friction (milling) reaction of H2O using a planetary ball mill machine with a stainless-steel vessel and balls. It was mediated by metals as an element of stainless steel of the ball mill and also promoted by mechanochemical processing.
