BiOBr nanoplates@TiO2 nanowires/carbon fiber cloth as a functional water transport network for continuous flow water purification

A novel BiOBr@ TiO2/carbon hybrid framework as a continuous flow sunlight water purification system has been reported in the present work. The BiOBr@ TiO2/carbon hybrid framework was fabricated via the sequential growth of TiO2 nanowires and BiOBr nanoplates on carbon fiber cloth. TiO2 nanowires interweaved with carbon fibers to form a porous network, while BiOBr nanoplates were arrayed on TiO2 nanowires. The obtained BiOBr@ TiO2/carbon hybrid framework possesses numerous micro/nanochannels between their adjacent one-dimensional building blocks, which can serve as an effective water transport network driven by capillary force. Furthermore, BiOBr@ TiO2/carbon hybrid frameworks exhibit impressive sunlight-driven photocatalytic activity and adsorption ability because of their enhanced sunlight absorption ability, efficient charge separation features, and mesoporous architecture. The excellent reusability and durability of the BiOBr@ TiO2/carbon hybrid frameworks have also been confirmed. A novel BiOBr@ TiO2/carbon hybrid framework based continuous flow sunlight water purification system with a high water purification efficiency (305.6 L h(-1) m(-2)) has been constructed in the present work. All the features make the BiOBr@ TiO2/carbon hybrid framework a promising material suitable for water purification.
