Efficient photoelectrochemical system for electrocarboxylation of 1,4-dibromobenzene with CO₂ using dye-sensitized photovoltaics.

ABSTRACT: Efficient photosynthesis using CO₂ and photovoltaics is an attractive solution to address environmental and energy crises. However, most attempts toward solar-driven CO₂ conversion have focused on producing fuels such as CO, CH₄, and ethanol by CO₂ electroreduction. Here, we demonstrate the efficient electrocarboxylation of CO₂ with 1,4-dibromobenzene (1,4-DBB) to value-added carboxylic acid esters driven solely by simulated sunlight. Employing a series-connected dye-sensitized photovoltaic and a silver (Ag) catalyst electrode with outstanding performance, a Faraday efficiency (FE) of 45.6% is achieved, which is close to the 47.7% FE of the common CO₂ electrocarboxylation reaction. After 14 h, the FE of the whole photoelectr
