▎ 摘　　要

Recent research on photochemical processes involving graphene oxide are summarized and analyzed. Such processes include the reduction of this oxide upon photoexcitation both with and without molecular or semiconductor photocatalysts, conversions of various substrates induced by graphene oxide as a photocatalyst (photoinitiator), and photocatalytic reactions, in which graphene oxide and the products of its reduction are cocatalysts. The major features and possible mechanisms of these reactions as well as areas for the further development of basic and applied research in this field of photochemistry of graphene oxide are discussed.
