Nanocrystalline EuVO4: synthesis, characterization, optical and photocatalytic properties

Abstract

In this paper europium vanadate (EuVO 4 ) nanoparticles were prepared via a sonochemical method based on the reaction between europium salt and ammonium metavanadate in water. Moreover, this method is free from any surfactant and organic solvents. The structural, morphological and optical properties of as-obtained products were characterized by techniques such as XRD, EDS, SEM, and UV-visible. The magnetic properties of as-prepared EuVO 4 nanoparticles were also investigated with vibrating sample magnetometer. To evaluate the catalytic properties of nanocrystalline europium vanadium oxide, the photocatalytic degradation of methyl orange under ultraviolet light irradiation was carried out.

Rational Design for the Synthesis of Europium Vanadate-Encapsulated Graphene Oxide Nanocomposite: An Excellent and Efficient Catalyst for the Electrochemical Detection of Clioquinol

“…It has been reported that EuVexhibits numerous advantages such as environmental benignity, cost-effectiveness, abundant oxygen vacancies, mixed valence state, intrinsic electrical conductivity, physiochemical stability, high ionic conductivity, and low toxicity. Notably, EuV with zircon-type structure has received significant consideration because of its favorability in technological applications. − …”

Effective Removal of Methylene Blue on EuVO4/g-C3N4 Mesoporous Nanosheets via Coupling Adsorption and Photocatalysis

“…Distinct lattice fringes can be observed in the HRTEM image ( Figure 1 c). The spacing of the lattice fringe was 0.362 nm, corresponding to the (200) crystal plane of tetragonal EV nanoparticle (PDF#15-0809) [ 14 , 17 , 18 ]. These results indicate that the intimate contact between EV nanoparticles and CN nanosheets successfully formed EVC heterojunctions [ 23 ].…”

“…Europium vanadate (EuVO 4 , EV) has been studied as a photocatalyst [ 13 , 14 ], laser material [ 15 ], and red phosphor [ 13 , 16 ] for its magnetism, thermal stability, and proper energy band gap. Lin et al prepared EV with different morphologies by the high-temperature electrochemistry method.…”

“…Vosoughifar synthesized EV nanoparticles via a precipitation approach; 82% of methyl orange was eliminated in 80 min under ultraviolet light irradiation [ 18 ]. In other research, EV nanoparticles were manufactured via a sonochemical method; 64% of methyl orange was removed after 70 min of UV irradiation [ 14 ]. Furthermore, a EuVO 4 -based heterojunction has been synthesized to promote its photodegradation efficiency.…”
