Photoelectrochemical (PEC) water splitting is an attractive strategy for the large‐scale production of renewable hydrogen from water. Developing cost‐effective, active and stable semiconducting photoelectrodes is extremely important for achieving PEC water splitting with high solar‐to‐hydrogen efficiency. Perovskite oxides as a large family of semiconducting metal oxides are extensively investigated as electrodes in PEC water splitting owing to their abundance, high (photo)electrochemical stability, compositional and structural flexibility allowing the achievement of high electrocatalytic activity, superior sunlight absorption capability and precise control and tuning of band gaps and band edges. In this review, the research progress in the design, development, and application of perovskite oxides in PEC water splitting is summarized, with a special emphasis placed on understanding the relationship between the composition/structure and (photo)electrochemical activity.

Die PEC‐Leistungen einiger typischer Perowskitoxid‐basierter Komposite/Hybride als Photoelektroden sind in Tabelle zusammengestellt . Die meisten PEC‐Apparaturen mit Perowskitoxid‐basierten Komposit‐Photoelektroden übertreffen solche aus den jeweiligen Einzelkomponenten, was auf das Vorliegen eines synergetischen Effekts schließen lässt.…”

Photoelektrochemische (PEC‐)Wasserspaltung bietet eine vielversprechende Möglichkeit zur Massenproduktion von erneuerbarem Wasserstoff aus Wasser. Zum Erzielen einer PEC‐Wasserspaltung mit hoher Effizienz für die Umwandlung von Solarenergie in Wasserstoff ist die Entwicklung kostengünstiger, aktiver und beständiger Halbleiter‐Photoelektroden von großer Bedeutung. Perowskitoxide als eine große Familie von Halbleiter‐Metalloxiden sind als Elektroden für die PEC‐Wasserspaltung intensiv untersucht worden; die Gründe hierfür sind ihre Häufigkeit, ihre hohe (photo)elektrochemische Stabilität, ihre Flexibilität bezüglich Zusammensetzung und Struktur, die eine Optimierung der elektrokatalytischen Aktivität ermöglicht, das überlegene Sonnenlichtabsorptionsvermögen sowie die präzise Steuer‐ und Abstimmbarkeit von Bandlücken und ‐kanten. In diesem Aufsatz werden die Fortschritte bei der Gestaltung, Entwicklung und Anwendung von Perowskitoxiden für die PEC‐Wasserspaltung zusammengefasst, mit besonderem Schwerpunkt auf dem Verständnis der Beziehung zwischen Zusammensetzung/Struktur und (photo)elektrochemischer Aktivität.

Summary Up to now, much effort has focused on developing the highly efficiency composite photocatalysts by introducing cocatalysts in the photocatalytic hydrogen production reaction, because the proper cocatalysts can reduce activation energy, provide active sites, and suppress the reverse reaction. The transition metal nickel and its compounds acting as cocatalyst have received intensive attention because of their structural stability, facile preparation, and high performance in hydrogen evolution reaction, and are expected to replace the function of noble metals. This review emphasizes on the latest progresses that design and construction of composite photocatalyst using Ni‐based cocatalyst for enhanced hydrogen production, such as metal nickel, nickel sulfide, and nickel phosphide, will be presented. Then, some preparation strategies and influence factors of Ni‐based cocatalysts on enhanced photocatalytic hydrogen production are elucidated in detail. Finally, some challenge and perspective on the highly active cocatalysts in the area of photocatalytic hydrogen production from water splitting are also given.
