Carbon fibers with infiltrated TiO2 nanocrystalline layers: photocatalytic performance

Original language description

This study examines the synergy of carbon fibers (CFs) and an infiltrated TiO2 nanocrystalline layer for photocatalytic degradation of methylene blue (MB). The CFs@TiO2 nanocomposite was developed using Vapour Phase Infiltration (VPI) of TiO2 into polyacrylonitrile fibers with 5-160 infiltration cycles and subsequently carbonized at 900 degrees C. This integrated production method enables precise integration of TiO2 and consistent coating over the fiber surface. SEM confirms the TiO2 layer thickening from 15.7 +/- 2.4 nm to 34.7 +/- 3.4 nm as the cycles increase from 40 to 160, while EDX and EDXRF indicate a similar rise in TiO2 content. XRD and Raman spectroscopy confirm the production of anatase TiO2 for VPI 40 c and higher, attributed to size-induced crystallization. UV-Vis DRS demonstrates that the optical bandgap varies with the cycle number in accordance with the development of the TiO2 layer. The outcomes of photocatalytic experiments under UV illumination indicate that the maximum degradation rate is achieved with the thickest coating. The CFs@TiO2 demonstrate exceptional cycle stability. This study emphasizes the potential of VPI-derived CFs@TiO2 as durable and effective photocatalysts.
