초록

Developing highly efficient and selective electrocatalysts for the chlorine evolution reaction (CER) in the chloralkali industry is of great importance. Here, we report the discovery of a new electrocatalyst for CER consisting of atomically dispersed Ru sites on surface tensile strained TiO2 (Ru-S-TiO2). The single-atom Ru species were stabilized on the strained TiO2 surface by strong metal-support interactions. The Ru-S-TiO2 is highly efficient, initiating CER at only 5 mV above the ECER, and has shown excellent stability for over 100 hours. It exhibited >95 % CER selectivity even in acidic media with low Cl− concentrations (0.2 M). Our results demonstrate that the strong metal-support interactions between the atomically dispersed Ru species and the strained TiO2 surface are crucial for the high catalytic activity, selectivity, and stability of Ru-S-TiO2 for CER. Ru-S-TiO2 holds great promise as a viable alternative to existing mixed metal oxides-based electrocatalysts for CER in the chloralkali industry. © 2024 Elsevier B.V.
