In this study, NiWO4 nanoparticles and polymer-based NiWO4 nanocomposites were synthesized and characterized. The nanocomposites showed nanoplate-like morphology and exhibited improved photocatalytic activity for the degradation of toxic dyes. Polymer materials such as polyaniline (PA) and polypyrrole acted as electron trap charge carriers and effectively inhibited fast electron recombination. The prepared NiWO4/PA nanocomposite exhibited a degradation efficiency of 94% for crystal violet and methylene blue dyes, indicating its potential application in wastewater treatment.
In this work, NiWO4 and polymer-based NiWO4 nanocomposites were synthesized by a simple hydrothermal method. The structure and functional groups of the composite materials were analysed by XRD and FTIR spectroscopy. HRTEM analysis confirms the composite materials with nanoplate-like morphology. Then the optical property was examined by UV-Visible spectroscopy. The polymeric materials of Polyaniline (PA) and Polypyrrole are composited with NiWO4 and act as electron trap charge carriers and inhibit the fast electron recombination in the photocatalytic degradation of toxic dyes. The polymer-supported NiWO4 excellently displays the competent electron-hole pairs separation and enhancement of light-reaping performance, thus reveals improved photocatalytic activity of toxic dyes. The crystal violet and methylene blue dyes were used for photocatalytic degradation of toxic dyes. The NiWO4/PA exhibits closely 94% degradation efficiency for both crystal violet and methylene blue dyes. This facilitates enhanced photocatalytic performance and prepared composite material used for wastewater treatment.
