Composites of metal-organic frameworks and carbon materials have been suggested to be effective materials for the decomposition of chemical warfare agents. In this study, we synthesized UiO-66-NH 2 /zeolite-templated carbon (ZTC) composites for the adsorption and decomposition of the nerve agents sarin and soman. UiO-66-NH 2 /ZTC composites with good dispersion were prepared via a solvothermal method. Characterization studies showed that the composites had higher specific surface areas than pristine UiO-66-NH 2 , with broad pore size distributions centered at 1-2 nm. Owing to their porous nature, the UiO-66-NH 2 /ZTC composites could adsorb more water at 80% relative humidity. Among the UiO-66-NH 2 /ZTC composites, U 0.8 Z 0.2 showed the best degradation performance. Characterization and gas adsorption studies revealed that beta-ZTC in U 0.8 Z 0.2 provided additional adsorption and degradation sites for nerve agents. Among the investigated materials, including the pristine materials, U 0.8 Z 0.2 also exhibited the best protection performance against the nerve agents. These results demonstrate that U 0.8 Z 0.2 has the optimal composition for exploiting the degradation performance of pristine UiO-66-NH 2 and the adsorption performance of pristine beta-ZTC.
