In this study, pure titanium oxide, magnesium hydroxide, and their composites TiO<sub>2</sub>/Mg(OH<sub>2</sub>) were prepared by thermal decomposition and precipitation of the titanium peroxo-complex and/or magnesium nitrate in an aqueous solution. The as-prepared composites were examined by XRD, XPS, HRTEM, and nitrogen physisorption. Their decontamination ability was tested on CWA surrogates and determined by high-performance liquid chromatography (HPLC) and gas chromatography coupled with mass spectrometry (GC-MS). Dimethyl methyl phosphonate (DMMP) was used as a G simulant for the nerve agents sarin (GB) and soman (GD) while 2-chloroRSC advances19542-19552https://www.ebi.ac.uk/biostudies/studies/S-EPMC9054062biostudies-literatureSynthesis and characterization of TiO<sub>2</sub>/Mg(OH)<sub>2</sub> composites for catalytic degradation of CWA surrogates.PMC9054062Stastny MHenych JKormunda MIssa GStengl VEderer JJanos PTolasz JfalseSynthesis and characterization of TiO<sub>2</sub>/Mg(OH)<sub>2</sub> composites for catalytic degradation of CWA surrogates.Surface catalyzed reactions can be a convenient way to deactivate toxic chemical warfare agents (CWAs) and remove them from the contaminated environment.
