采用水蒸气法对Rh 2-yCryO 3/GaN：ZnO进行了气相光催化分解水的实验研究。样品已被放置在μ反应器中，并在太阳光照射下释放氢和氧。本实验证明了用气相实验研究太阳能活性材料和水裂解反应机理的可能性。通过改变水分压和反应器温度，表明了相对湿度对活性的高度影响。
Rh2-yCryO3/GaN:ZnO has been tested for gas phase overall photocatalytic water splitting by dosing water vapor. The sample has been deposited in a mu-reactor and evolves hydrogen and oxygen under illumination of solar light. This experiment proves the possibility to study solar active materials and the mechanism of the water splitting reaction with gas phase experiments. The high impact of the relative humidity on the activity has been shown by changing the water partial pressure and the reactor temperature.
