Engineering of a Hybrid g-C3N4/ZnO-W/Cox Heterojunction Photocatalyst for the Removal of Methylene Blue Dye

Robust hybrid g-C3N4/ZnO-W/Cox heterojunction composites were synthesized using graphitic carbon nitride (g-C3N4) and ZnO-W nanoparticles (NPs) different concentrations of Co dopant. The prepared by simple low-cost coprecipitation methods. fabricated catalyst was explored investigated various characterization techniques such as FTIR, XRD, FESEM EDX. surface morphology the as-prepared nanocomposites with particle sizes in range 15–16 nm validated SEM analysis. elemental composition confirmed EDS Photocatalysis a photon sole energy source is considered challenging approach for organic transformations under ambient conditions. photocatalytic activity heterojunctions tested photodegrading methylene blue (MB) dye presence sunlight. reduced band gap composite 3.22–2.28 eV revealed that incorporation metal ions played an imperative role modulating light absorption applications. as-synthesized g-C3N4/ZnO-W/Co0.010 suppressed charge recombination ability during degradation dye. ternary C3N4/ZnO-W/Co0.010 showed impressive performance 90% MB visible within 90 min irradiation, compared to outcomes achieved other compositions. Lastly, good recyclability mechanical stability over five cycles, confirming them promising photocatalyst options future.
