The present work demonstrates the unique construction of polymeric graphitic carbon nitride (g-C 3 N 4) contained nonhierarchical zinc-vanadium oxide (ZnV 2 O 6) composite for light-emitting diode (LED) aided photocatalytic degradation of an organic pollutant, tetracycline hydrochloride (TC). The g-C 3 N 4 was prepared by pyrolysis of urea whereas ZnV 2 O 6 and 1:1 (ZnV 2 O 6 /g-C 3 N 4) composite were prepared by hydrothermal process. The as-synthesized catalysts were subjected to scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), dynamic light scattering (DLS) analysis, X-ray diffraction analysis, Fourier-transform infrared (FTIR) analysis, UV-Visible spectroscopy, and photoluminescence (PL) to unravel the physical, chemical, and photo-intrinsic characteristics. The 1:1 (ZnV 2 O 6 /g-C 3 N 4) composite exhibited the maximum TC degradation (87.2%) over the individual components. The systematic investigations revealed that 20 mg of 1:1 (ZnV 2 O 6 /g-C 3 N 4) catalyst was optimum to degrade 20 mg/L of TC with 9 W of LED irradiation up to 125 min. The 1:1 composite retained its catalytic efficiency for three consecutive runs that mark its on-site application. The as-proposed system for TC degradation is exclusive for the fabrication of electronically compatible composite that results in delayed recombination of photo-charges and promotes rapid electron migration within the composite, thereby accelerating the photodegradation.

“…Recently, the theory of single-atom catalyst reported provides guiline for solving the bottleneck in the application of RE ions in catalysis. [1,61,62] It is well known that single-atom catalysis is different from ordinary nano-catalysis. When the particle dispersion reaches the atomic level, some new characteristics of the catalyst will be induced, such as the increase of free energy, more unsaturated coordination environment, and metal support interaction, which makes it possible to greatly improve the photocatalytic performance of a single-atom catalyst.…”

“…The doping of rare-earth ions is regarded as a facile technique to improve the photocatalytic properties of semiconductors owing to its ability in the modulation of energy band gap and the control of the recombination of electron-hole pairs. [22][23][24] Through introducing the rare-earth ions (i.e., Gd 3+ , Y 3+ , Sm 3+ ) into the metal oxide nanoparticles, Radhika et al revealed that the photocatalytic properties of these nanomaterials were significantly modified. [25,26] Via use of the upconversion (i.e., UC) emissions of Er 3+ /Yb 3+ -codoped BiOBr nanosheets, Zhang et al found that the resultant products can degrade RhB efficiently upon visible and NIR light irradiation.…”

In spite of this, one of the unavoidable issues of photocatalysis is how to take advantage of solar energy efficiently. As we know, the sunlight can be roughly divided into three parts, that is, ultraviolet, visible and near-infrared (NIR) light, in which they take around 5%, 45%, and 50% energy of the sunlight, respectively. [6,7] To date, these widely used photocatalysts, such as ZnO, WO 3 , and TiO 2 , suffer from narrow absorption edge, where the energy originating from visible and NIR light is wasted, resulting in dissatisfied photocatalytic properties. [8][9][10] In order to tackle this shortage, researchers tried to find out other semiconductors and some nano-sized compounds, such as CaAl 5 Fe 7 O 19 , ZnS-CdS, and SiO 2 -TiO 2 , which were promising candidates for photocatalytic and antibacterial applications, were proposed. [11][12][13][14] Thereby, searching for novel semiconductors is a facile and efficient route to develop highly efficient photocatalytic materials.Over the last decades, considerable attention has been attracted in bismuth containing semiconductors since they exhibit promising applications in photocatalysis owing to their superiorities including high stability, suitable energy band gap (i.e., E g ), and nontoxicity. [15,16] Shi et al. reported that the Bi 5 OI 7 and BiO 5 I 2 semiconductors with admirable photocatalytic activities can utilize both ultraviolet and visible lights. [17] As a member of bismuth containing semiconductors, the investigation on the photocatalytic properties of BiOX (X = F, Cl, Br, and I), which displays unique matlockite structure with [XBiOOBiX] layers, has been intensively performed. [18,19] Particularly, with the help of weak nonbonding van der Waals interaction along the c-axis, [Bi 2 O 2 ] 2+ slabs with positive valence are interleaved by means of two halide ions, leading to the production of internal electric field along the caxis. [18] Note that, the occurrence of the internal electric field enables the separation of electron-hole pairs more efficiently which gives rise to admirable photocatalytic behaviors of BiOX. At present, it has been revealed that the BiOX compounds can capture both ultraviolet and visible lights to photodegrade pollutants (i.e., RhB, methyl orange). [20,21] Nevertheless, these currently developed BiOX photocatalysts still own some deficiencies, such as the harvest of NIR light is insufficient and A facile strategy is put forward to improve the photocatalytic activity of BiOF nanoparticles by simultaneously exploiting doping and upconversion engineering. The Er 3+ /Yb 3+ -codoped BiOF nanoparticles are synthesized via using high-temperature solid-state reaction route. Through employing firstprinciples density functional theory, one knows that the electronic structure of BiOF host is greatly impacted by Er 3+ and Yb 3+ ions doping. Excited by 980 nm, bright upconversion emissions are seen in prepared compounds and their maximum intensities are obtained when x = 0.04. Furthermore, the photocatalytic capacity of the designed n...
