To create better materials to defend against Chemical Warfare Agents (CWAs), we must fundamentally understand the chemistry occurring on the surface of materials designed to defeat CWAs. Cu<sub>x</sub>O impregnated into BPL carbon is currently used in gas mask filters, and CuO nanoparticles have been proven to cause room temperature decomposition of dimethyl methylphosphonate (DMMP). To determine the effects of the CuO and the carbon, mesoporous FDU-15, a porous carbon was loaded with varying amounts of CuO. Along with mesoporous pure CuO was synthesized. These materials were characterized using multiple imaging, diffraction, and surface-sensitive measurements to fully understand them. This series of mesoporous materials were then tested using fixed feed temperature-programmed modulation (FFTPM) after exposure to DMMP to determine what products were produced at different temperatures. In addition to a DRIFTS study to determine what products were formed on the surface at room temperature.
