Abstract
Various metal-organic frameworks (MOF) are highly effective catalysts for detoxifying chemical warfare agents (CWAs). In this study, we reported a MOF-loaded cellulose sponge for fast degradation of CWAs simulant. In situ growth of UiO-66-NH2 onto γ-Glycidoxypropyltrimethoxysilane (GPTMS) modified cellulose sponge was achieved. This sponge featured high porosity (88%), high specific surface area (310.5 g/m2) and low density (36 mg/cm3). The UiO-66-NH2 functionalized cellulose sponge showed excellent catalytic activity for detoxifying 4-Nitrophenyl Phosphate (DMNP) and the half-life was as short as 9 min.Entities:
