Recent development on MoS2-based photocatalysis: A review

MoS2-based photocatalysts attract wide attention as they possess a suitable band gap for visible-light harvesting, making it a promising earth-abundant photocatalyst for hydrogen production, environmental remediation, and photosynthesis. However, the rapid recombination of photogenerated electron-hole pairs, limited quantity of active edge sites, and difficult photocatalyst separation and recycling hinder the practical application of this material. In this review, recent development of MoS2-based photocatalysts in various photocatalytic applications is summarized. In addition, possible approaches to enhance photocatalytic activity and separate photocatalysts from reaction media are discussed to provide a future direction in highly efficient photocatalyst design.
