Enhanced simulated sunlight photocatalytic performance in K2Ti6O13/g-C3N4 heterojunction.

In this study, K₂Ti₆O 1 3 (KTO) nanowires were doped with carbon (CKTO) via a novel solid-phase approach at 800^∘C for the first time using ethanol, KF, and TiO₂. In addition to the lower sintering temperature, a shorter insulation period was achieved compared to the conventional solid-phase method. Furthermore, by combining and calcining CKTO and g-C₃N₄, a CKTO/g-C₃N₄ heterojunction composite was produced. The rate at which CKTO/g-C₃N₄ photocatalytically degraded methylene blue was higher than those of pure CKTO and g-C₃N₄. Our study indicates that adding g-C₃N₄ enhances photocatalytic performance by reducing the recombination rate of photogenerated electron–hole pairs and narrowing the bandgap of the CKTO/g-C₃N₄ heterostructure. This paper presents a novel method for creating KTO composites in an eco-friendly and productive manner for the photocatalytic degradation of organic colors. [ABSTRACT FROM AUTHOR]
