Metallic Bi Nanocrystal‐Modified Defective BiVO4 Photoanodes with Exposed (040) Facets for Photoelectrochemical Water Splitting

Time to split: Metallic Bi-modified BiVO4 photoanodes with oxygen vacancies as an effective photoelectrocatalyst are prepared. The oxygen vacancies can increase photogenerated electron capture and the adsorption of H2O. The Bi nanocrystals are beneficial for the photo-response range and separation of photogenerated carriers. This obtained BiVO4 photoanodes exhibit excellent performance for photoelectrochemical water splitting.

Understanding the Oxygen Evolution Reaction on a Two-Dimensional NiO2 Catalyst

Understanding the Oxygen Evolution Reaction on a Two‐Dimensional NiO2 Catalyst

More than a nickel: Density functional theory is employed to model the mechanisms of several oxygen-evolution reactions. It is found that the catalytic activity of NiOOH (composed of partially hydrogenated NiO2 2D sheets) is not limited to the defect sites and the edges, as usually assumed, but that many reaction centers are available on the NiO2 surface itself.
