Morphology tuning is one of the innovative techniques to overcome challenges of a pristine graphitic carbon nitride (g-C3N4) as a photocatalyst. In this study, a unique pipe-like C3N4 have been fabricated using a facile, environmentally friendly and scalable approach by treating dicyandiamide (DCDA) with ethylene glycol and nitric acid. The pipe-like C3N4 samples have been possessed unique structural morphology with enhanced visible light-harvesting ability, efficient charge separation and large surface area with more reactive sites. These enhanced properties of the pipe-like C3N4 have been exhibited superior complete photocatalytic degradation of methylene Blue (MB) within 30 min under visible light (λ > 420 nm) compared to the bulk C3N4. In addition, the pipe-like C3N4 have good photostability and efficiency (96%) and potential applications in other fields such as photoelectrochemistry, electrocatalysis, and optoelectronic devices.

独特的管状C3N4,具有增强的光催化降解有机污染物的能力

形态调整是克服原始石墨化碳氮化碳(gC 3 N 4)作为光催化剂的挑战的创新技术之一。在这项研究中,通过使用乙二醇和硝酸处理双氰胺(DCDA),采用一种简便,环保且可扩展的方法制造了独特的管状C 3 N 4。管状C 3 N 4样品具有独特的结构形态,具有增强的可见光捕获能力,有效的电荷分离和较大的表面积和更多的反应位。管状C 3 N 4的这些增强的性能与本体C3N4相比,在可见光(λ> 420 nm)下30分钟内,亚甲基蓝(MB)具有优异的完全光催化降解能力。此外,管状C 3 N 4具有良好的光稳定性和效率(96%),并且在其他领域(如光电化学,电催化和光电器件)中具有潜在的应用前景。
