The mechanism of CsPbBr3 quantum dots promoting COF-366-Co for Photo-Coupled CO2 Electroreduction

Caption

CsPbBr3 quantum dots were encapsulated into a COF-366-Co host to form interfacial electric field, which not only promotes the utilization efficiency of the photo-generated carriers for CO2 reduction. Thus, the optimal CsPbBr3@COF-366-Co-2 exhibited a CO Faradaic efficiency of 93.4% at −0.7 V vs. RHE and a TOF of 3395.5 h−1 at −0.9 V under visible light, exceeding the values recorded in the dark.
