“…By contrast, in the CF-nZVI-JE/PDS system, fluorescence color of the solution changed from red to orange and to green during the initial 30 min. Afterward, the green fluorescence became weak with delaying the reaction time, suggesting the gradual degradation of the formed intermediate products (Wu et al 2020). This was consistent with the UV-Vis result that Rh B was degraded into some intermediate products firstly and then the intermediate products were further mineralized in the CF-nZVI-JE/PDS system.…”

In this study, a novel peroxydisulfate (PDS) activator (CF-nZVI-JE) was prepared via in-situ loading nano zero-valent iron (nZVI) on Juncus effusus (JE) followed with wrapping a layer of cellulose film (CF). The CF-nZVI-JE had the same 3D structure as the JE, being easy to separate from aqueous solution. The loaded nZVI existed single nanoparticles with a size of 60–100 nm except chain-type agglomeration of nanoparticles due to the stabilization of JE fibers. The activation performance of the CF-nZVI-JE for PDS was evaluated with Rhodamine B (Rh B) as a representative pollutant. Under the optimal activating conditions, the degradation rate of Rh B reached 99% within 30 min in the CF-nZVI-JE/PDS system. After five cycles, the degradation rate of Rh B was still over 85%, suggesting that the CF-nZVI-JE had good reusability. More interestingly, SO4·− and ·OH radicals were simultaneously detected in the CF-nZVI-JE/PDS system, but only SO4·− existed in the JE-ZVI/PDS system, suggesting the different activation mechanism. Meanwhile, the introduction of CF not only facilitated to the mineralization of Rh B but also significantly reduced the release amount of iron ions. Hence, the CF-nZVI-JE can be employed as a promising PDS activator for the treatment of organic wastewater.

“…Photodegradation of dyes has attracted considerable attention from researchers [ 44 , 45 , 46 ]. We chose two kinds of dyes: fluorescein sodium salt and rhodamine 6G as the dye examples for the photodegradation experiment, as both dyes are commonly used in this kind of experiment, and also, represent the common organic pollution [ 47 , 48 , 49 ]. Detailed information about dye molecular structure, toxicity, and molecular mass can be found in Table S1 .…”

The development of multifunctional nanomaterials has received growing research interest, thanks to its ability to combine multiple properties for severing highly demanding purposes. In this work, holmium oxide nanoparticles are synthesized and characterized by various tools including XRD, XPS, and TEM. These nanoparticles are found to emit near-infrared fluorescence (800–1100 nm) under a 785 nm excitation source. Imaging of the animal tissues was demonstrated, and the maximum imaging depth was found to be 2.2 cm. The synthesized nanoparticles also show the capability of facilitating dye (fluorescein sodium salt and rhodamine 6G) degradation under white light irradiation. The synthesized holmium oxide nanoparticles are envisioned to be useful for near-infrared tissue imaging and dye-degradation.
