Thermodynamics of CO adsorption on the zeolite Na-ZSM-5 A combined microcalorimetric and FTIR spectroscopic study
Literature Information
Carbon monoxide was found to adsorb, at room temperature, on Na-ZSM-5. IR spectra of adsorbed CO showed two main bands at 2176 and 2112 cm-1, which were assigned to the C–O stretching mode of Na+···CO and Na+···OC adducts, respectively. The complex structure of these bands suggested that cation sites in Na-ZSM-5 are not all identical. Further proof of the presence of slightly different cation sites was obtained by IR spectroscopy of adsorbed carbon dioxide. Microcalorimetry of adsorbed CO, in conjunction with IR spectroscopy and volumetric adsorption data, allowed a detailed thermodynamic study to be carried out on the CO/Na-ZSM-5 system. CO adsorption was found to follow a Langmuir-type isotherm. The (exothermic) adsorption process showed a differential heat of adsorption of ca. 27 kJ mol-1. The enthalpy change in the formation of Na+···CO and Na+···OC species was found to be ΔH°=-28 and ΔH°=-24 kJ mol-1, respectively, while the value of TΔS°=-41 kJ mol-1 was derived for both adsorption modes.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
