Overview

Randomized trial investigates optical and electrocatalytic properties in quaternary sulfides, suggesting novel applications.

Key Points

  • The aim is to explore the optical, photoelectric, and electrocatalytic properties of quaternary sulfides RE3M1–xSnS7.
  • Synthesized by direct reaction at 1000 °C; characterized using powder and single-crystal X-ray diffraction.
  • Further characterization using X-ray photoelectron and electron paramagnetic spectroscopy.
  • Optical band gaps ranged from 1.5 to 2.5 eV; La3Fe0.5SnS7 shows suitable photocurrent density for photoelectric energy conversion.
  • La3Mn0.5SnS7 and La3Cd0.5SnS7 exhibit moderate second harmonic generation and high laser damage thresholds.
  • La3Ni0.5SnS7 demonstrates electrocatalytic activity for the oxygen evolution reaction.
