A comparative study of hydrogen production on micro- and nano metal oxides was carried out. The maximum amounts of hydrogen produced on nano-Al2O3 in radiation-thermal processes were 2.9, 3.36 and 5.4 x 1018 molecules at 373, 473 and 573 K with 3 h time at 373 and 473 and 2 h time at 573 K. Maximum amounts of hydrogen produced on nano-SiO2 in radiation-thermal processes were 1.7, 2.5 and 3.2 x 1018 molecules at 373, 473 and 573 K with 3 h time at 373 and 473 and 2 h time at 573 K. The maximum amounts of hydrogen produced on nano-ZrO2 in radiation-thermal processes were 11.44, 13.1 and 15.2 x 1018 molecules at 373, 473 and 573 K with 3 h time at 373 and 473 and 2 h of time at 573 K. The radiation-chemical yields of hydrogen in radiation-thermal with nano-Al2O3, nano-SiO2 and ZrO2 were 2.5–6.1, 1.07 to 3.10 and 4.8 to 13.6 molecules/100eV. The activation energies with nano-Al2O3, nano-SiO2 and ZrO2 were 25.2, 17.2 and 20.1 kJ/mol. The order of hydrogen production observed was ZrO2 > Al2O3 > SiO2. The hydrogen production mechanism confirmed the formation of various energetic species, resulting in the formation of hydrogen.
