Abstract: A submicron-sized Pickering miniemulsion system stabilized by carbon quantum dots solid nanoparticles for biphasic catalysis is disclosed, which breaks the existing limits for homogenization of the immiscible biphasic system and overcomes the issues for big size of solid particles-stabilized emulsion droplets. A method for producing the carbon quantum dot-based catalysts and a process of establishing the Pickering miniemulsion system for biphasic reaction with enhanced catalytic efficiency are also disclosed. The carbon quantum dot-stabilized Pickering miniemulsion features a pH-responsive behavior, with a reversible transition between the emulsification and demulsification, triggering the easy & facile product separation and emulsifier/catalyst recycling in one reaction vessel.

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.
