Black NiO powders were prepared by a hydrothermal method. Moreover, the visible light-driven Ag 3 PO 4 /NiO photocatalyst composites were successfully synthesized by in situ precipitation method. These samples were structurally characterized by X-ray diffraction and Rietveld refinement. The strong interaction between the phases and the defects in the samples was affected by the formation of the composites, as identified by Fourier transform infrared spectroscopy and Raman spectroscopy. UV–vis diffuse reflectance spectroscopy exhibited enhanced light absorption for all Ag 3 PO 4 /NiO composites, suggesting the effective interaction between the phases. Moreover, field-emission scanning electron microscopy images revealed the presence of NiO microflowers composed of nanoflakes in contact with Ag 3 PO 4 microparticles. The composite with 5% NiO presented enhanced photocatalytic efficiency in comparison with pure Ag 3 PO 4 , degrading 96% of rhodamine B (RhB) dye in just 15 min under visible light; however, the recycling experiments confirmed that the composite with 75% NiO showed superior stability. The recombination of the electron–hole pairs was considered for the measurement of the photoluminescence of the samples. These measurements were performed to evaluate the possible causes for the difference in the photocatalytic responses of the composites. From these experimental results, possible photocatalytic mechanisms for RhB degradation over Ag 3 PO 4 /NiO composites under visible-light irradiation were proposed.

“…Strong adsorption of cationic dye MB in S3 under dark conditions can be related to positive-negative charge attraction between the Ag 3 PO 4 surface and MB molecules, respectively, due to the presence of oxygen vacancies. 54,55 In all cases, absorption and degradation took less than 5 min.…”

“…[ 146,211,279,280 ] In this context, photodegradation is a promising alternative for treating water contaminated with POPs not easily removed using conventional treatment systems. [ 91,281,282 ] In this direction, functionalized nanofibers membranes have been successfully employed for POPs photodegradation, according to examples displayed in Table 2 , owing to their high surface‐to‐volume ratio, and the possibility to be modified with a wide range of catalysts materials.

“…Therefore, their destruction through photodegradation is usually preferable, once dyes can be converted into harmless products. [ 280,282 ] In this regard, in 2015 researchers modified cellulose electrospun nanofibers with CdS NPs via chemical bath deposition to photodegrade Rhodamine B (RhB) dye under visible light irradiation. [ 284 ] The modification method enabled a uniform dispersion of the NPs onto the surface of the nanofibers, as shown in Figure a(i).…”

Micro‐ and nanofibers produced by electrospinning and solution blow spinning (SBS) are highly suitable platforms for diverse applications due to their advantageous properties, including the high surface area to volume ratio, high porosity, and flexibility. To render them additional functionalities, distinct pre‐ or post‐modification processes have been proposed for modifying such micro‐ and nanofibers with 0D, 1D, 2D, and 3D nanostructures. The pre‐modification requires the addition of 0D–3D nanostructures (or their precursors) into the polymeric phase before the spinning process, which can demand laborious solubilization and requires changes in experimental spinning parameters, with impact on morphology, spinnability, and properties. Post‐modification methods, on the other hand, enable the fabrication of composite fibers without the need to optimize the spinning parameters, allowing a simple and efficient surface modification. Herein, recent advances on post‐modification methods of spun fibers, including wet chemistry, grafting, crosslinking, click chemistry, oxidations, hydrolysis and reduction strategies, dip‐coating, layer‐by‐layer, electro/air‐spray, atomic layer deposition, and plasma techniques aiming at the surface functionalization with 0D–3D nanostructures are surveyed. Recent results, trends, and challenges on the application of such surface‐modified fibers for environmental, industrial, and medical applications, including as adsorbent and filtering membranes, catalysts for pollutants degradation, and wearable sensors are examined.
