A plasma in liquid state was applied as a light source in photocatalysis. The effects of liquid phase plasma irradiation were investigated for hydrogen evolution on the photocatalysts. The photocatalytic activities for hydrogen production from liquid phase plasma and UV light irradiation were compared. SrTiO 3 perovskite photocatalysts which prepared by a sol‐gel method with high temperature calcining were introduced in the photocatalytic reaction. The effects of the metal loading on the perovskite photocatalysts were also evaluated in photocatalysis. A small amount of hydrogen was generated in the photo‐decomposition by irradiation of plasma into water without photocatalysts. The rate of hydrogen evolution by photocatalysis using plasma was increased on TiO 2 and SrTiO 3 perovskite photocatalysts. The photocatalytic activity was improved significantly with the metal loading on SrTiO 3 perovskite photocatalysts.
