Abstract: Disclosed are a general-purpose fluorescent fluid photochemical microreactor and a manufacturing method therefor by means of 3D printing, belonging to the technical field of photochemical reactor research. By using a transparent photosensitive resin and the strong space building capacity of 3D printing, a photochemical microreactor having both a light-collecting channel and a reaction channel is prepared. By means of introducing a light-collecting substance in a fluid form into a light channel, not only can play the role of light collection and wavelength conversion, which solves the difficulty of traditional photochemical reactors of light source matching, but also the light-collecting substance can be flexibly changed so as to meet the requirements of different photochemical reactions in the reaction channel, which greatly expands the application range of the reactor.
