Probing the basicity of oxide surfaces by FTIR spectroscopy of isocyanic acid generated insitu by thermal decomposition of nitromethane
Abstract
Infrared spectroscopy of isocyanic acid generated insitu by the thermal decomposition of nitromethane provides an efficient and easy method to probe the basic strength of the surface of oxides. The frequencies of the adsorbed isocyanate species are directly correlated with the heats of adsorption of carbon dioxide determined by microcalorimetry.
