Interfacial charge transport and band structure modulation via defect engineering in calcium-doped g-C3N4 nanorods for enhanced photocatalysis and selective wastewater dye degradation

Key Points

• Enhanced photocatalysis occurs through improved interfacial charge transport mechanisms, leading to significant degradation rates.
• The study highlights an increase of 47% in dye degradation efficiency with specific calcium doping in g-C3N4 nanorods.
• Defect engineering is essential for modulating the band structure, which improves photocatalytic performance under visible light.
• Improvements in this area may enable better wastewater treatment solutions, addressing pollution challenges.
