Combined with another catalyst, such as platinum, that can produce hydrogen gas from water, the system can duplicate the water splitting reaction that occurs during photosynthesis.
结合上其他从水中产生氢气的催化剂如铂，这个系统就能复制在光合作用中所发生的水分解反应。

The key component in the process is a catalyst -- cobalt metal, phosphate and an electrode, placed in water -- that produces oxygen gas from water, while another catalyst produces hydrogen gas.
