Carbon vacancy modified g-C3N4 hollow tubes-iron oxide composite for photocatalytic application

Popis výsledku v původním jazyce

Graphitic carbon nitride (g-C3N4) has emerged as a non-metal, visible-light-active semiconductor with considerable potential in environmental photocatalysis. This research presents a straightforward method for creating carbon vacancy-modified g-C3N4 hollow tubes, resulting in enhanced performance. Utilizing single-step static air polymerization, we produced tubes with superior physicochemical and electronic properties, as confirmed by various characterization analyses. Remarkably, calcining the precursor at 550 ℃ greatly improved the photocatalytic efficiency in degrading methylene blue compared to other tubes synthesized under different conditions and bulk g-C3N4. Electrochemical tests revealed increased conductivity, higher charge carrier density, and an optimized conduction band edge, all contributing to the material&apos;s improved efficiency. Incorporating Fe2O3 further boosted the efficiency and stability, forming by Z-scheme heterojunction. Kinetic and thermodynamic parameters confirmed the feasibility of activity on the Fe2O3 modified surface. These features position the material as highly promising for dye photodegradation and broader environmental applications. © 2024 Elsevier Ltd
