Data from: Candle-Soot Derived Photoactive and Superamphiphobic Fractal Titania Electrode

Attached file provides supplementary data for linked article. Carbon soot is one of the oldest materials known for its hydrophobic properties, robustness, and availability, making it an ideal material for use in various applications. The drawbacks, however, are the loose structural binding between constructing carbon nanoparticles and the amorphous nature of soot itself. In this paper, we present a facile chemical vapor deposition (CVD) method that maintains the soot template structural integrity and enables its modification into a highly photoactive, self-cleaning titania fractal network. The results show that the small air pockets available on the surface combined with the salinization process produces a TiO2 fractal network with superamphiphobic properties. Given the high surface area of the fractal network structure and titania's well-known photocatalytic activity, the designed surfaces were assessed for their photocatalytic decoloration activities. The results showed that the soot template derived TiO2 films can offer enormous potential in many different applications where self-cleaning and/or high surface area and photoactive properties are required.随附文件为本关联文章提供补充数据。 碳烟（carbon soot）是已知最古老的材料之一，因其疏水特性、结构稳健性与易得性而广受认可，成为诸多应用场景的理想备选材料。然而其存在显著缺陷：构成碳烟的碳纳米颗粒之间结构结合松散，且碳烟本身呈无定形结构。本研究提出一种简便的化学气相沉积（CVD）方法，可维持碳烟模板的结构完整性，并将其改性为高光活性、自清洁型二氧化钛（titania）分形网络。 研究结果表明，表面存在的微小气穴与盐化工艺相结合，可制备出具备超双疏（superamphiphobic）特性的二氧化钛分形网络。鉴于该分形网络结构具备高比表面积，且二氧化钛的光催化活性早已广为人知，本研究对所设计的表面开展了光催化脱色活性评估。结果显示，以碳烟为模板制备的二氧化钛薄膜，在需要自清洁、高比表面积以及光活性特性的诸多应用场景中具备巨大应用潜力。
