Uranium, as the principal component of nuclear waste, poses significant environmental challenges. Photocatalytic adsorption has emerged as a promising method for theeffective removal of dissolved uranium from aqueous solutions. Nonetheless, currently available photocatalytic materials predominantly exist in powder or coating forms, which limits their efficiency in rapidly capturing uranium within flowing nuclear wastewater. In response to this limitation, the present study reports the development of a novel catalytic architecture comprising homogeneous heterogeneous titanium dioxide (TiO2) nanocones coupled with multilayer carbon fibers. Specifically, the homogeneous heterojunction formed between anatase-phase TiO2 nanoparticles and rutile-phase nanocones facilitates efficient electron transport, while the multilayer support structure not only enhances recyclability but also improves the interfacial contact area for the reaction process. This catalyst demonstrates remarkable performance by removing approximately 92.97% of uranium from 100 mg L−1 uranium-containing wastewater within 10 minutes and exhibits rapid regeneration capability, maintaining over 90% uranium removal efficiency after 10 consecutive cycles. This work offers aneffective strategy for uranium removal from wastewater, thereby contributing to the environmental sustainability of the nuclear energy industry.  \n1. Introduction  \nNuclear energy is considered a relatively ideal clean energy source and plays a critical role in ensuring the sustainable use of global energy resources.1,2 However, the nuclear power generation industry produces substantial volumes of uraniumcontaining radioactive wastewater throughout the uranium mining and nuclear fuel utilization processes, posing signi􀀁 -cant environmental risks.3–5 Due to the inherent radioactivity and the stable speciation of pollutants in nuclear wastewater, traditional biological metabolism6,7 and physical adsorption methods8,9 face considerable challenges in rapidly removing uranium from high-concentration nuclear effluents. In contrast, photocatalytic materials exhibit notable advantages such as structural stability under radiation exposure and the ability to transform pollutant species,10,11 enabling the efficient reduction of dissolved uranium in water to insoluble solid phases for rapid removal.12–14 Nonetheless, conventional  \naHigh-Tech Institute of Xi'an, Xi'an, Shaanxi, China.
