摘要	Herein, carbon-doped titania nanostructures (C/TNTs) were prepared via a facile hydrothermal route using different carbon sources, i.e., carbon sheets (CSs), acetylene black (AB)(,) graphene oxide (GO), and reduced graphene oxide (rGO), as doping agents. The morphological characteristics, crystalline nature, nanometric size, and phase purity were determined by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and powder X-ray diffraction (XRD), which revealed a tube-like morphology with a similar to 30 nm size, anatase nature, and titanium-oxygen structure, respectively. The as-synthesized nanostructured materials were investigated as photocatalysts under sunlight irradiation for the degradation of methylene blue (MB), a model dye, and for the inactivation of Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive), which are representative microorganisms. Compared with that of a bare titania nanocatalyst (60 %), the photocatalytic degradation efficiency of the as-prepared C/TNT nanostructures was remarkably high (approximately 74 to 94 %) when utilizing a 10 mg of catalyst under sunlight for 40 min. Moreover, these nanocatalysts exhibit exceptional antibacterial properties by restraining the growth of bacteria. The antibacterial analysis demonstrated that the C/TNT nanocatalysts had a significant impact on all bacteria as opposed to bare TNTs. These results revealed that doping with carbon enhanced the photocatalytic activity of TNTs under sunlight irradiation against MB dye as well as selected microbes, especially the rGO/TNT nanocatalyst, which exhibited superior photocatalytic and antibacterial activity. In addition, the rGO/TNTs have good recycling ability, with an MB degradation ratio of more than 81 % after five cycles. We hope that this high activity of the C/TNT nanocatalyst under sunlight irradiation for organic dye degradation and bacterial inactivation implies that hydrothermal synthesis allows for the preparation of efficient and low-cost carbon-doped photocatalysts for a wide range of environmental applications.
