Emerging frontiers of nickel-aluminium layered double hydroxide heterojunction for photocatalysis

Abstract

The unique superiorities of nickel-aluminium layered double hydroxide (Ni-Al LDH)-based heterojunction, i.e., large special area, tunable bandgap and morphology, abundant reaction sites, high activity, selectivity, and photostability, etc, render them extremely promising for photocatalytic applications. Given the importance and benefits of Ni-Al LDH-based heterojunction in photocatalysis, now is a good moment to give a summary of Ni-Al LDH-based heterojunction for photocatalytic applications. In this frontier, we thoroughly described the material design for Ni-Al LDH-based heterojunction, along with their recent developments in various photocatalytic applications, i.e., H2 evolution, CO2 reduction, and pollution removal. Moreover, the most recent advancements, difficulties, and future prospects of Ni-Al LDH-based heterojunction for photocatalytic applications were emphasized and thoroughly examined. Undoubtedly, in the near future, scientific researchers will put their relentless efforts to exploit the new Ni-Al LDH-based heterojunction for high-performance photocatalytic applications.
