Wafer‐Scale 2D High‐Entropy Transition Metal Dichalcogenide Thin‐Film Catalysts for Efficient and Durable Photoelectrochemical Hydrogen Production

Key Points

• The aim is to explore how configurational entropy influences the activity and stability of TMDs in hydrogen production.
• Utilized p-Si photocathodes for testing catalytic performance and stability over 100 hours.
• Analyzed effects of configurational entropy on catalytic activity and photocarrier transport.
• p-Si photocathode exhibited remarkable photocurrent density and stability for over 100 hours, outperforming single-metal TMDs.
• Demonstrated that configurational entropy significantly enhances phase stability and efficiency.
