Sulfur-containing compounds are odorous and/or deleterious chemicals in the workplace, hospital, and home. In this context, a series of solid multifunctional materials that selectively degrade organosulfur compounds has been developed. These materials include 1) a robust aerobic oxidation catalyst (NOxBrxH+) embedded within various porous polymeric matrices, 2) polyoxometalates (POMs) incorporated within metal organic frameworks (MOFs) to form POM@MOF hybrid materials, and 3) a polymeric polyniobate K12[Ti2O2][SiNb12O40]●22H2O (KSiNb) that is an efficient hydrolysis catalyst. Both POM@MOFs and NOxBrxH+ facilitate oxidative degradation of deleterious sulfur compounds using only O2 as an oxidant at ambient temperature and pressure. The geometrical and electronic structures of some of these multifunctional materials have been characterized by XANES and EXAFS while diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) provide complementary structural information.//
