Abstract Lead halide perovskites are promising for artificial photosynthesis but suffer from aqueous instability. Here, we stabilize CsPbI3 quantum dots within a hydrophobic chlorine-functionalized covalent organic framework through multisite atomic-chlorine passivation, forms dual Cl-Pb coordination and Cl-I halogen bonding at the interface. This suppresses ionic migration while creating a gas-solid-liquid triphase interface for enhanced O2 diffusion.

1 Introduction Turbulent mass transfer is a fundamental phenomenon and directly influences the efficiency of both separation[1] and reaction,[2, 3] the two major operations in chemical and many other process industries.[4] Enhancing mass transfer is an effective way of process enhancement aiming at inherently and significantly increasing the efficiency of the processes.[5] Experimental studies showed that mass transfer is strongly affected by the inside geometric structure of the channel of...
