Copper-doped Manganese Dioxide has been synthesised through a simple hydrothermal method at different doping levels. The materials have characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM) to determine composition, structure, morphology. All the Cu doped MnO2 are found be single phased. Their electrochemical properties as cathode for Zinc-ion batteries studied cyclic voltammetry (CV), galvano-static charge/discharge (GCD) impedance spectroscopy (EIS), using 3 M ZnSO4 + 0.3 MnSO4 solution electrolyte. 3.8% shown highest initial capacity of 379.5 mAh g−1 0.02 A·g−1, 304.4 mA h 0.5 A g−1, but experienced fast fading with poor retention 56.8% after 100 cycles. 7.4% gives lower capacity, while 5.9% shows higher discharging (320.0 mAh·g−1 A·g−1 269.3 A·g−1) improved stability (85.8% cycles), better than non-doped electrode (284.4 252.1 76.7%). samples show satisfactory rate capability cycling is not ideal, which may relate needle like morphology nanoscale particle size. CV tests revealed that process mainly diffusion controlled. zinc ion coefficient tested in range 10-12 cm2·s-1 from both EIS showed same trend their capacity. Doping Copper reduced polarization on electrode, reversibility, evidenced reduction redox peak potential difference 0.31 0.24 V 1.1 mV·s−1, 0.45 5 mV·s−1. Whilst cell resistance increased 1.78 Ω 7.39 cycling, resistances all Cu-doped cathodes reduced, indicating electronic conductivities cycling. These results indicate Cu-doping effective increase conductivity materials, reduce during charge discharge, improve cathode.

Highlights•An eco-friendly and cost-effective procedure for the synthesis of Silver-doped Zinc Oxide/Magnesium Oxide Nanocomposite.•Silver-doped Nanocomposite as an excellent photocatalyst degradation organic dyes.•Low cell bio-toxicity Nanocomposite.•Application Mentha pulgium extract biosynthesis Nanocomposite.AbstractThis research attempted to prepare silver-doped zinc oxide/magnesium oxide nanocomposite (Ag-doped ZnO/MgO-NCP) using pulegium plant extract. The synthesized NCP was investigated by X-ray diffraction analysis (XRD), Fourier Transform Infrared (FT-IR), Field Emission Scanning Electron Microscope (FESEM), Energy dispersive spectroscopy (EDX), Mapping, UV–Visible analyses. XRD data displayed cubic crystal structures silver & magnesium a hexagonal framework oxide. Also, FESEM PSA images pointed out, that average size spherical morphology is about 10–16 nm, while EDX confirmed attendance Zn, Mg, Ag, O elements. Under UVA light, we tested photocatalytic activity Methylene blue (MB) Rhodamine B (RhB) dyes in various temperatures (400, 500, 600 °C). results test percentage MB dye pH = 9, amount ∼30 mg, concentration ∼1 × 10 −5 M 98 %. We also evaluated cytotoxicity on cancer CT-26 line through MTT method obtained IC50 value 250 μg/mL.Graphical abstract
