    Abstract: Free radicals, as a type of essential components of troposphere atmosphere, play different roles in photochemical reaction, owing to their diverse properties, and has gained heightened interests in recent years. The review attempted to summarize the sources of·OH, HO2·, RO·, RO2·, NO3·and environmental persistent free radicals in the atmosphere, their function in photochemical reactions, as well as the key influencing factors. Besides, the potential promising research directions of free radicals in photochemical reactions were proposed simultaneously. Consequently, the work was of immense significance to gain comprehensive insights into the core scientific issues pertaining to atmospheric oxidative capability and the reaction mechanism of free radicals in photochemical reactions.
