Hydrogen production was studied in the -radiolysis of aqueous HSO solutions containing oxide powder of AlO, SiO, TiO or ZrO. The observed yields of final product H increased with relative amounts of oxide powder in the solutions and exhibited a particular HSO concentration dependence, which was different for each oxide species and its amount. The addition of a small amount of CHOH to a HSO aqueous solution with oxide powder was quite effective for increasing the final product yields of H. The obtained results revealed that heterogeneous systems composed of oxide powder and aqueous HSO solution were more efficient for producing H molecules in -radiolysis than homogeneous systems without oxides.
