A Strategy for Separating and Recycling Solid Catalysts Based on the pH‐Triggered Pickering‐Emulsion Inversion

Abstract

Turn you inside out: A novel method for performing in situ separation and recycling of submicrometer-sized solid catalysts is developed based on the pH-triggered inversion of Pickering emulsions (see scheme; o = oil, w = water). Solid catalysts can be recycled 36 times without significant loss of activity. The method differs from conventional methods in terms of speed, energy consumption, catalyst separation, and recycling effectiveness.
