摘要：
In this study, we present a novel heterojunction photocatalyst (TiO2-TTCOF) 2-TTCOF) boosting charge transfer for visible- light-driven CO2 2 to CO conversion without photosensitizer or sacrificial agents. The 10% TiO2-TTCOF 2-TTCOF heterojunction photocatalyst is able to catalyze CO2 2 conversion, resulting in a highest CO production rate of 139.1 mu mol g- 1 with a selectivity of 96% and O2 2 production rate of 73.1 mu mol g- 1 . Additionally, time-resolved fluorescence decay spectra confirmed the heterostructure between TTCOF and TiO2 2 can promote photoelectron transfer. The ATR-IFTS spectra indicated the photocatalytic reaction pathway.
