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.
