Crystallization-suppressed annealing preserves amorphous TiO2 interfaces and strengthens Pt coupling for photocatalysis

Key Points

• The study aims to explore how crystallization-suppressed annealing affects TiO2 interfaces and their photocatalytic performance.
• Used crystallization-suppressed Ar annealing on TiO2 interfaces
• Created alkali-assisted, N-deficient g-C3N4/Pt composites
• Evaluated hydrogen evolution under visible light
• The NVCN/Pt/aT composite achieved 2.1 times higher H2 evolution compared to previous methods
• Strengthened Pt-support coupling improved electron extraction efficiency
