TL;DR - A study in Advanced Materials demonstrates defect-guided Pt–S anchoring for efficient solar hydrogen production with only 0.084 wt% platinum. The approach improves catalyst stability and atom efficiency while supporting scalable film fabrication.

• Sulfur-rich defects at ZnIn₂S₄/ZnS interfaces selectively anchor isolated Pt through strong Pt–S coordination.
• Hydrogen evolution reached 22.43 mmol·g⁻¹·h⁻¹ under visible light and 91.35 mmol·g⁻¹·h⁻¹ under full-spectrum illumination.
• Spectroscopy and first-principles calculations indicate that Pt–S sites enhance interfacial electron extraction and optimize hydrogen adsorption.
• Catalyst films achieved an areal hydrogen flux of 331.34 mmol·m⁻²·h⁻¹, and the anchoring strategy generalized to other ZnIn₂S₄ heterojunctions.
