Description	Manganese(IV) oxides were prepared by homogeneous hydrolysis of potassium permanganate with 2-chloroacetamide and direct reaction of potassium permanganate with manganese(II) sulfate in aqueous solutions. Synthesized manganese(IV) oxides were characterized using Brunauer-Emmett-Teller (BET) surface area and Barrett-Joiner-Halenda porosity (BJH), X-ray diffraction (XRD), infrared spectroscopy (IR), and scanning electron microscopy (SEM). These oxides were taken for an experimental evaluation of their reactivity with sulfur mustard (HD or bis(2-Chloroethyl)sulfide), soman (GD or (3,3'-dimethylbutan-2-yl)-) and VX agent (S-[-(diisopropylamino)ethyl]-O-ethyl-methylphosphonothionate). The degree of conversion for sulfur mustard and agent VX is very good for both samples and come up to 95% and 99%, respectively. In the contrast to sulfur mustard and agent VX, degradation of soman was only 56% of the cryptomelane-type MnO2 and 18% of the birnessite-type MnO2.
