In this study, a novel copper nanozyme (CNZ) was synthesized by a mild way and characterized by scanning electron microscopy and Fourier transform infrared spectroscopy (FTIR). The as-fabricated CNZ exhibited typical peroxidase activity toward 2, 2′-azinodi-(3-ethylbenzthiazoline)-6-sulfonate. We successfully applied CNZ for the degradation of methyl orange pollutants. Under the optimum conditions (pH, 3.0; T, 60 °C; H2O2 concentration, 200 mM; dosage of CNZ, 8 mg), 93% of the degradation rate could be obtained in less than 10 min. Furthermore, the nanozyme exhibited excellent reusability and storage stability. All these experimental results suggested that CNZ is a powerful catalyst for industrial wastewater treatment.

“…All photocatalytic investigations were carried out under parallel conditions on sunny days between 10 am and 2 pm. Open borosilicate glassware was used for the reaction (Balakrishnan et al 2017). In the degradation studies, 20 mg of the synthesized photocatalyst was suspended in 50 mL of an aqueous solution comprising FCF dye at a concentration of 1 X 10 − 5 M. At the start of the experiment, before visible light irradiation, to attain adsorption-desorption equilibrium between the pollutants and tungsten oxide nanoparticles, the solution was magnetically stirred in the dark for 30 minutes.…”

For the rst time, the effect of gemini based twin-tail and conventional surfactant on tungsten oxide nanostructures and their e cacy for the elimination of the organic pollutant is studied. The tungsten oxide nanostructures were synthesized by a simple hydrothermal route in the presence of C 14 TAB and gemini based twin-tail surfactant. The impact of using these special shape and size directing agents for the synthesis of nanostructures was observed in the form of different shapes and sizes. The tungsten oxide web of chains type nanostructure was obtained using C 14 TAB in comparison to the cube shaped nanoparticles through twin-tail surfactant. On contrary, the twin-tail surfactant provides sustainable and controlled growth of cube shape nanoparticles of size ~ 15 nm nearly half of the size ~ 35 nm obtained using conventional surfactant C 14 TAB, respectively. For the detailed structural features, the Williamson-Hall analysis method was implemented to nd out the crystalline size and lattice strain of the prepared nanostructures. Owing to the strong quantum con nement effect, the WO 3 cube shaped nanoparticles with an optical band gap of 2.69 eV of the prepared nanoparticles showed excellent photocatalytic e cacy toward organic pollutant (Fast green FCF) compared to the web of chain nanostructures with an optical band gap of 2.66 eV. The mechanism has been discussed in detail in the respective section. The ability of the prepared systems to decompose the organic pollutant (Fast green FCF) in water was tested under visible light irradiations. The percentage degradation was found to be 94% and 86% for WO 3 cube shaped nanoparticles and WO 3 web of chains, respectively. The simplicity of the fabrication method and the high photocatalytic performance of the systems can be promising in environmental applications to treat water pollution.
