Chemical warfare agent simulant DMMP reactive adsorption on TiO2/graphene oxide composites prepared via titanium peroxo-complex or urea precipitation

[Display omitted] •Two undemanding methods were used to prepare TiO2/GO nanocomposites.•GO addition increased adsorption capacity of the composites.•GO addition resulted in an enhanced reactive dissociation of DMMP.•Redox state of GO is crucial parameter for adsorption and degradation. Two water-based methods were used to produce TiO2/graphene oxide (GO) nanocomposites with 1 and 2 wt.% GO. Both procedures exclude the use of organometallic precursors, as well as the high-pressure and high-temperature treatments, which facilitate pure and energy efficient synthesis amenable for larger scale synthesis. Nanocomposites with narrow (
