Abstract For the application of CO 2 as an energy storage material, a H system has been proposed based on interconversion and formic acid (or formate). However, losses are inevitable in conversion electrical to chemical (≈70 % efficiency) (≈40 efficiency). To overcome these significant losses, we developed formate for direct generation electricity. In this paper, report aqueous redox flow battery using homogeneous Ir catalysts with ‐formate pair. The exhibited maximum discharge capacity 10.5...

The surface orientation dependence of the dissociation formic acid and adsorption structures formate on single-crystalline Cu surfaces at 300 K were investigated by infrared reflection absorption spectroscopy (IRAS) combined with density functional theory (DFT) calculations. A monotonic increase in peak intensity OCO symmetric stretching (νs(OCO)) mode was observed Cu(111), indicating exposed Cu(111) a uniform state terrace sites. In contrast, multiple νs(OCO) peaks step sites detected...

To suppress CO2 emissions, technologies that incorporate capture, utilization, and storage are being actively developed. Particularly, batteries using redox reactions one of the most promising systems combine energy conversion storage. However, stoichiometric metal restrict capacity previously proposed systems. Applying catalyst-mediated is expected to provide flexible control without dependence on content. Herein, we report novel aqueous flow battery CO2–formate with a bifunctional...
