Manganese dioxide (MnO2)-chitin–hybrid material was prepared by a facile “one-pot” synthesis method. MnO2–chitin hybrid was used for the effective removal of methylene blue (MB) from liquid solution as model for wastewater treatment. The hybrid obtained was characterized by field emission scanning electron microscopy and energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction and thermogravimetric analysis. The effect of pH and temperature were studied. MnO2–chitin hybrid showed high performance for oxidative decolorization and removal of MB. Typically, 25 mL of MB (20 mg/L) can be completely decolorized in 2.5 min with 8.5 mg of the MnO2–chitin hybrid. The hybrid material exhibited excellent recyclability and durability with the degradation value of 99% for MB after ten consecutive cycles.
