一氧化氯，为氧氯化合物，化学式为ClO。它在臭氧损耗中起着重要的作用。

在臭氧层中，氯原子与臭氧分子发生反应，产生氧分子与一氧化氯 。

re Chlorine monoxide is a chemical radical with the chemical formula ClO. It plays an important role in the process of ozone depletion. In the stratosphere, chlorine atoms react with ozone molecules to form chlorine monoxide and oxygen.

This reaction causes the depletion of the ozone layer. This reaction can go on and the ClO· radicals can go on to react as such:
