Engineered nanomaterials continue to stimulate wide interest in diverse disciplines including electrochemistry. Particularly, rare-earth-metal vanadate (REVO) is widely applied in the development of electrocatalyst. Therefore, we develop a new strategy for the fabrication of nanoarchitecture for an electrochemical sensor. A simple physical mixture method which allows precise control of the composition, structure, and surface morphology was adapted to synthesize europium vanadate/graphene oxide (EuV/GO) nanocomposites. The EuV/GO nanocomposites were analyzed using modern techniques and were potentially applied to electrochemical detection of neurodegenerative drug clioquinol (CQL). As electrode material for electrochemical sensor, EuV/GO showed a wide linear range (0.005−331; 345−1320 μM) and very low limit of detection (0.001 μM) with excellent selectivity. This nanoarchitecture prevents the electrode from fouling as well as acts as a bridge for rapid electron/ion transfer. In addition, the nanocomposites provide abundant active sites and large surface area to improve the channels between electrocatalyst and electrolyte. The practical applicability was revealed by quantifying the CQL concentration in biological sample, recommending this new approach as a reasonable alternative to the other traditional techniques. This REVO opens a new opportunity to build design for the family of electrode materials, which are used in electrochemical applications.

“…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 ].…”

“…This prepared adsorbent exhibited good selective adsorption properties and high removal efficiency for U(VI) [ 17 ]. 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 ].…”

In this study, we first manufactured ultrathin g-C3N4 (CN) nanosheets by thermal etching and ultrasonic techniques. Then, EuVO4 (EV) nanoparticles were loaded onto CN nanosheets to form EuVO4/g-C3N4 heterojunctions (EVCs). The ultrathin and porous structure of the EVCs increased the specific surface area and reaction active sites. The formation of the heterostructure extended visible light absorption and accelerated the separation of charge carriers. These two factors were advantageous to promote the synergistic effect of adsorption and photocatalysis, and ultimately enhanced the adsorption capability and photocatalytic removal efficiency of methylene blue (MB). EVC-2 (2 wt% of EV) exhibited the highest adsorption and photocatalytic performance. Almost 100% of MB was eliminated via the adsorption–photocatalysis synergistic process over EVC-2. The MB adsorption capability of EVC-2 was 6.2 times that of CN, and the zero-orderreaction rate constant was 5 times that of CN. The MB adsorption on EVC-2 followed the pseudo second-order kinetics model and the adsorption isotherm data complied with the Langmuir isotherm model. The photocatalytic degradation data of MB on EVC-2 obeyed the zero-order kinetics equation in 0–10 min and abided by the first-order kinetics equation for10–30 min. This study provided a promising EVC heterojunctions with superior synergetic effect of adsorption and photocatalysis for the potential application in wastewater treatment.
