Role of Hydrothermal Reaction Time on Defect-and Strain-Engineered Few-Layered MoS2 Nanoflowers for Tunable Band Gap and Enhanced Visible-Light Photocatalysis

Key Points

• To investigate how varying hydrothermal reaction times affects the properties of MoS2 nanoflowers and their efficiency in photocatalysis.
• Synthesis of MoS2 nanoflowers using different hydrothermal reaction times.
• Characterization of structural and optical properties of the nanoflowers.
• Assessment of photocatalytic activity under visible light.
• Longer hydrothermal reaction times lead to improved defect and strain properties in MoS2.
• Nanoflowers exhibit tunable band gaps, enhancing their photocatalytic efficiency.
• Optimized reaction times significantly increase pollutant degradation rates under visible light.
