The research was conducted in order to improve the hydrogen generation efficiency of the electrical plasma technology from tap water by using TiO₂ photocatalyst, mixed Cu - TiO₂ powder, and mixed Ni - TiO₂ powder as the catalysts. Experiments were performed with the pulsed power and nitrogen carrier gas. The result has shown that the hydrogen concentration with the presence of TiO₂ powder was created higher than that of without using photocatalyst. The hydrogen concentration with using TiO₂ was 3012ppm corresponding to the applied voltage of 16㎸, while it without using the TiO₂ was 1464ppm at the same condition . The effect of TiO₂ powder was strongly detected at the applied voltages of 15㎸ and 16㎸. This phenomena might be resulted from the co-effect of the pulsed power discharge and the activated state of TiO₂ photocatalyst. The co-effect of the mixed catalysts such as Cu-TiO₂ and Ni-TiO₂ (the mixed photocatalyst TiO₂ and transition metals) were also investigated. The experimental results showed that, Cu and Ni powder dopants were greatly enhancing the activity of the TiO₂ photocatalyst. Under these experimental conditions the extremely high hydrogen concentrations at the optimal point were produced as 4089ppm and 6630ppm, respectively.
