Hollow crystalline red phosphorus for efficient visible-light photocatalytic hydrogen evolution from pure water splitting

Key Points

• Hydrogen evolution efficiency reached 2.4 mmol h-1 under visible-light illumination in water splitting activities.
• Key evidence shows that hollow crystalline red phosphorus significantly enhances photocatalytic performance.
• Assessment involved photocatalytic experiments that tested various materials for visible-light activity.
• These findings may enable improved photocatalysts for sustainable hydrogen production, particularly in renewable energy applications.
