Tuning the local chemical environment of ZnSe quantum dots with dithiols towards photocatalytic CO₂ reduction.

ABSTRACT: Sunlight-driven CO₂ reduction to renewable fuels is a promising strategy towards a closed carbon cycle in a circular economy. For that purpose, colloidal quantum dots (QDs) have emerged as a versatile light absorber platform that offers many possibilities for surface modification strategies. Considerable attention has been focused on tailoring the local chemical environment of the catalytic site for CO₂ reduction with chemical functionalities ranging from amino acids to amines, imidazolium, pyridines, and others. Here we show that dithiols, a class of organic compounds previously unexplored in the context of CO₂ reduction, can enhance photocatalytic CO₂ reduction on ZnSe QDs. A short dithiol (1,2-ethanedithiol) activates the QD surface for CO
