Abstract
In this work, the impacts of triethanolamine (TEOA) on the performance of photochemical CO2 reduction were investigated in a simple homogeneous system. We demonstrates that CO2 can be converted into CO coupling with the decomposition of triethanolamine in TEOA aqueous solution without other additives under light irradiation. About 7.5 μmol CO product is achieved within 7 h with a maximum apparent quantum yield (AQY) of 0.086% at 254 nm. The isotope labelling experiment confirms that CO product originates from the reduction of CO2 rather than the decomposition of TEOA. In addition, the photochemical system exhibits excellent stability, no obvious inactivation is observed during long-term photochemical CO2 reduction reaction. This work provides a deep understanding of the effects of TEOA on the performance of photocatalytic CO2 reduction. Upon utilizing TEOA as a sacrificial electron donor in photocatalytic system, the contribution of TEOA must be considered once evaluating the catalytic activity of catalysts.
