Tailoring Lewis acid sites in lanthanum-doped carbon nitride for H 2 O 2 synthesis and efficient photocatalytic degradation of antibiotics
Key Points
Over 95% tetracycline removal is achieved within just 1 hour of photocatalytic treatment.
The introduction of lanthanum enhances Lewis acid sites, facilitating hydrogen peroxide generation under visible light.
Catalysis shows stable continuous-flow mineralization, crucial for environmental applications.
Enhancing rare-earth Lewis sites offers promising green synthesis options, yet the approach needs further exploration.
Abstract
La-doped carbon nitride introduces La-N coordination and Lewis acid sites, enabling synchronous H2O2 generation/activation under visible light. The catalyst achieves >95% tetracycline removal within 1 h and stable continuous-flow mineralization, highlighting rare-earth Lewis site engineering for solar-driven purification and green synthesis.
