Synthesis of solution processed f-CNT@Bi2S3 hybrid film coated linen fabric as a free-standing textile structured photo catalyst

Abstract

A unique metallic carbon hybrid film, synthesized with synchronized distribution of bismuth sulfide (Bi2S3) and exfoliated multiwall carbon nanotubes (MWCNTs), has been proposed for use as freestanding textile electrodes in photo catalysts. The defect-rich morphology of Bi2S3 nanowire decorated MWCNT hybrid enhances the photocatalytic activity, electronic properties, cyclic stability, and electron pathways. The proposed f-CNT@Bi2S3-hybrid linen fabric electrode demonstrated a defect-rich morphology synchronized with high electrical conductivity. These properties greatly enhanced the photocatalytic activity and electron transfer. The high photocatalytic activity is attributed to the synergistic effect of the high electron affinity of MWCNTs and the structural distortion caused by Bi2S3 nanowires. Degradation of methylene blue dye was accelerated owing to the elevated activity of Bi2S3 nanowires, which provides fast absorption of contaminants and reduction of oxidative species. Our proposed system of metallic carbon freestanding textile electrode opens the broad applications of textile-based photochemical devices.
