研究目的
To fabricate SnS2/SnS heterojunction nanosheets via a facile and environmental route for improved light-assisted electrochemical water splitting performance.
研究成果
The SnS2/SnS heterojunction nanosheets showed good performance in light-assisted electrochemical water splitting due to the generation of more electron–hole pairs through harvesting of more light wavelengths. They are a promising candidate for low-cost and environmentally friendly photo-electrocatalysis.
研究不足
The study focuses on the fabrication and performance of SnS2/SnS heterojunction nanosheets for light-assisted electrochemical water splitting, but further evaluation is needed to assess their practical application potential.
1：Experimental Design and Method Selection:
The SnS2/SnS heterojunction nanosheets were synthesized by the solvothermal and heat treatment methods.
2：Sample Selection and Data Sources:
SnCl4·5H2O and thiourea were used as precursors.
3：List of Experimental Equipment and Materials:
FESEM (JSM-7000F), TEM (JEOL model JEM2100), XRD (Bruker D8 Advance), Raman spectrometer (JY T64000), XPS (PHI5000 Versaprobe).
4：Experimental Procedures and Operational Workflow:
The mixture was transferred into a Te?on-lined autoclave and heated at 180°C for 24 h, followed by heat treatment at 500°C for 30 min under Ar atmosphere.
5：Data Analysis Methods:
The crystal phase properties were analyzed with XRD, and the chemical composition was determined by XPS.
