US 12,544,742 B1 · Sulfurized perovskite nanosheets, synthesis and uses thereof

Abstract

The present invention relates to the field of renewable energy and photocatalysis (e.g. photocatalytic water splitting for hydrogen production), specifically focusing on sulfurized perovskite compounds, perovskite nanosheets, and synthesis method and uses thereof. The present invention relates to perovskite nanosheets comprising LaXOnS3-n, wherein X is a metal selected from Fe, Co, Mn, Cu, Zn, or Ni; and wherein 0<n<3. Further, the present invention explores the perovskite nanosheets to improve efficiency, stability, and light absorption in solar-driven hydrogen generation applications. The present perovskite nanosheet enhances visible light absorption, charge carrier mobility, and catalytic activity, making it useful for large-scale hydrogen production.
