Abstract

The base heterogenization is crucial for the practical applications of metal-organic frameworks (MOFs) as catalytic filters, such as masks or protective suits, for the deconstruction of chemical warfare agents (CWAs). Here, we performed the hydrolysis of a phosphate-based nerve agent simulant in the presence of different amine-based bases (i.e., a small organic molecule, dendrimers, and linear and branched polymers) using a Zr-MOF, NU-901, with 4,8-connected scu topology. Remarkably, the catalytic performances of NU-901 using the less-volatile branched polymers and dendrimers are comparable to the volatile N-ethylmorpholine solution.
