Accelerated Decoloration of Organic Dyes from Wastewater Using Ternary Metal/g-C3N4/ZnO Nanocomposites: An Investigation of Impact of g-C3N4 Concentration and Ni and Mn Doping

Wastewater from many sectors that contains hazardous organic pollutants exacerbates environmental contamination. Consequently, outstanding photocatalytic substances can successfully degrade are needed to provide pollution-free water. From this perspective, zinc oxide/g-C3N4-based composites desirable due their low cost, strong reactivity, and friendliness. So, in the current investigation, sequences of Mn/g-C3N4/ZnO (Mn/GZ) Ni/g-C3N4/ZnO (Ni/GZ) nanocomposites (NCs) containing different concentrations (wt.%) g-C3N4 were made via co-precipitation process. The chemical makeup morphological characteristics produced ascertained techniques transmission electron microscopy (TEM), scanning (SEM), energy-dispersive X-ray (EDX), Fourier transform infrared (FTIR), photoluminescence (PL), UV spectrophotometry. Methyl orange (MO) Eriochrome Black T (EBT) dyes used as target assess composite materials’ effectiveness. Compared g-C3N4/ZnO g-C3N4, Mn/GZ Ni/GZ NCs displayed better activity. improved efficiency might be credited synergistic interactions at ZnO interface result a more efficient separation conduction photo-induced charges. Furthermore, Ni/Mn atoms act facilitators improve electron–hole pair NCs. found incredibly stable, with consistently high dye decoloration over five catalytic cycles. Hence, could potentially very effective adaptable photocatalysts for wastewater pollutants.
