The development of narrow-band-gap photoanodes is crucial for efficient water-splitting oxygen evolution reactions. Manipulation of crystal and electronic structures, as well as composition-dependent properties, are extensively researched to develop effective water splitting technologies. High-throughput techniques are proposed as potential rapid approaches to explore the composition-structure-performance relationship in ternary vanadates.
The development of narrow-band-gap photoanodes is a major challenge in the quest for efficient water-splitting oxygen evolution reactions. The monoclinic scheelite BiVO4 makes ternary vanadates increasingly attractive by highlighting their intriguing characteristics. Manipulation of crystal and electronic structures, as well as composition-dependent properties, are researched extensively in order to develop effective water splitting technologies. Exploration of the composition-structure-performance relationship is of great significance but requires a heavy workload. Thus, high-throughput techniques attract attention as potential rapid approaches to such exploration. Here, we summarize state-of-the-art screening of ternary vanadates over broad compositional gradient ranges via high-throughput techniques. The relationship between composition and photo-electrochemical performance is also highlighted. We then consider challenges and perspectives for the rational design of advanced ternary vanadates designed for the water-splitting oxygen evolution reaction and propose implementation of high-throughput techniques to expedite such development.
