“…Hence, it is clear that sacrificial anode electrolysis allows producing tailored nanostructures, depending on their applications. Still regarding photodegradation field, Isaev and colleagues proposed electrosynthesized cuprite nanostructures (Cu 2 ONPs) as photocatalysts for the oxidation of azodyes under visible light treatment. Performing the synthesis under different hydrogen pressures, they obtained crystalline Cu 2 ONPs which were active, towards the discoloration of the chrome dark blue azodye solution, upon visible light treatment.…”

Electrochemical synthesis of transition metal nanoparticles (NPs) and related oxides is highly appealing, as it affords nanomaterials with high purity and dimensional control by properly setting only few experimental parameters. The resurgence of electrochemical routes to NPs can be traced back to seminal works by the Reetz's group, about 25 years ago. Despite many advantages, this method has intrinsic limitations, mainly related to the use of organic solvents, which may limit real-life applications of the as-prepared NPs. Therefore, an important current issue in the electrosynthesis of these systems regards the preparation of aqueous and long-lived colloids. In this Review, we provide an overview of the most promising electrosyntheses of colloidal nanomaterials; real-life applications of electrochemically produced NPs will also be commented on.

“…Mahamuni and co-workers prepared ZnO quantum dots using the sacrificial anode electrochemical method [18]. The ZnO [19], Cu 2 O [20], CuO [21], Au/AgI [22] have been successfully synthesized by electrochemical method. We have recently synthesized hexagonal shaped CuO NP in bulk [2], cubic shaped Zn 2 SO 4 [23] and large size ZnO NP [3,4] by hybrid sacrificial anode electrochemical-thermal route.…”

The nanoparticles (NP) ZnO and CuO were synthesized by electrochemical-thermal method. The influence of cetyltrimethylammonium bromide (CTAB) on size and morphology of NP was evaluated. They were characterized by powder X-ray diffraction spectroscopy (XRD), scanning electron microscopy (SEM), UV-Visible absorption spectroscopy. The average crystallite size and the average grain size of NP decreased with CTAB concentration. The CTAB significantly affected the morphology of CuO and ZnO NP. The regular spindle shape of CuO transformed into irregular spherical shape and the homogeneity in the morphology of spherical ZnO NP was lost with increase in CTAB concentration. The effect of morphology and size of ZnO on its photocatalytic activity was evaluated by subjecting methylene blue (MB) dye to photocatalytic degradation under the irradiation of UV light. The color removal of MB dye during electrolysis was monitored by UV-Visible spectroscopy. The highest photocatalytic activity was noticed for ZnO 10 mM CTAB.
