Composite MOF foams: the example of UiO-66/polyurethane.

Composite MOF foams were prepared using a direct synthesis of UiO-66 over a polyurethane foam template. Under optimized conditions, the composite materials maintained the macrostructure and flexibility of the polyurethane foam, and exhibited the microporosity, high surface area, and adsorption properties of the UiO-66. The composite MOF foam has hierarchical porosity and high adsorption capacity for benzene and n-hexane, maintaining more than 70% of the adsorption capacity of the UiO-66.
