In this study, the microwave assisted methodology was employed to produce uniformly distributed platinum nanoparticles decorated with graphane oxide-chitosan. The capacity of methylene blue removal of these nanohybrids at room temperature was examined via adsorption. Characterizations of these novel nanoadsorbents were accomplished using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). The X-ray diffractogram of the Pt NPs@CSGO displayed an ordinary structure of face-centered cubic (FCC). Adsorbance measurement results represented significant performance increases for all these novel nanohybrids for methylene blue removal. However, Pt NPs@CSGO hybrid was one of the best nanoadsorbent compared to others produced in this study. Our results presented that the one of highest methylene blue adsorption capacity belongs to the Pt NPs@CSGO, which was 194.6 mg/g, can be considered as an outstanding capacity. Its equilibrium was accomplished in 55 min. Furthermore, all these Pt NPs are reusable materials for the methylene blue removal application because they sustained 74.02 % of the initial efficiency after six successive adsorptions–desorption cycles.
