Effective hydrogen generation using water-n-hexane-ZrO2 system: Effect of temperature and radiation irradiation time

Abstract

There is a great demand for economic green hydrogen fuel production and, consequently, hydrogen generation by water radiolysis of a hexane-water system on ZrO2 surface is presented at various temperatures. The radiation-catalytic decomposition of the hexane-water had increased at high temperatures i.e. ranging from 300 to 673 K. It caused an increase in the yield of hydrogen production in the radiation-catalytic decomposition of hexane-water. It was observed that at a temperature of T = 673 K a chain mode of conversion of the key products of hexane-water resulted in molecular hydrogen. Finally, the maximum yield of hydrogen was 188.5 molecule/100 eV with n-ZrO2 + C6H14(ads)-water (0.003 g: 0.0051 g: 0.0015 g) at 673 K.
