Toward Base Heterogenization: A Zirconium Metal–Organic Framework/Dendrimer or Polymer Mixture for Rapid Hydrolysis of a Nerve-Agent Simulant

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
