Solar Water Oxidation by a Visible‐Light‐Responsive Tantalum/Nitrogen‐Codoped Rutile Titania Anode for Photoelectrochemical Water Splitting and Carbon Dioxide Fixation

Abstract

The front cover artwork is provided by the Ishitani and Maeda group at the School of Science at the Tokyo Institute of Technology (Japan). The image shows CO2 reduction and H2 production coupled to water oxidation by a photoelectrochemical system based on a Ta/N codoped rutile TiO2 anode under sunlight.

Molecularly engineered photocatalyst sheet for scalable solar formate production from carbon dioxide and water

“…9 Therefore, particular effort has been focused on the development of standalone hybrid photoelectrochemical (PEC) cells, which can also couple CO 2 RR with water oxidation. [10][11][12][13][14] However, hybrid PEC cells suffer from scale-up problems due to the pH gradient and IR drops occurring during the PEC reaction. 15 Colloidal systems using particulate photocatalysts are an emerging alternative to PEC configurations as they benefit from a simpler design and potentially lower cost.…”
