Abstract

A novel S-scheme heterojunction photocatalyst based on 2D g-C₃N₄ nanosheets modified by 1D TiO₂ nanotubes (TNTs) has been successfully prepared. The successful fabrication of 2D/1D g-C₃N₄/TNTs S-scheme photocatalysts by hydrothermal method and thermolysis processes was confirmed through a variety of characterization methods (HR-TEM, XRD, and FTIR). The g-C₃N₄/TNTs S-scheme heterojunction expressed advances in the degradation of nitrogen oxide (NO), a harmful environmental pollutant. In detail, 2D/1D g-C₃N₄/TNTs heterojunctions demonstrated the most effective decomposition of NO and their ability to remain stable under visible-light conditions, achieving the removal of over 66.44% of NO at 550 ppb during the entirety of the experiment.

g‐C3N4/TiO2二维/一维异质结作为高效光催化剂脱除NOx

成功制备了一种基于1D TiO2纳米管修饰的二维g-C3N4纳米片的新型s型异质结光催化剂。通过各种表征方法（HR-TEM、XRD和FTIR）证实了水热法和热分解法制备2D/1D g-C3N4/TNTs -scheme光催化剂的成功。g-C3N4/TNTs S-scheme异质结在降解有害环境污染物氮氧化物（NO）方面取得了进展。2D/1D g-C3N4/ tnt异质结对NO的分解效果最好，且在可见光条件下保持稳定，在整个实验过程中，在550 ppb的条件下，NO的去除率超过66.44%。

期刊介绍： The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
