Zeolite and Cuttlebone by Near-Ambient Pressure XPS
Near ambient pressure - X-ray photoelectron spectroscopy (NAP-XPS) is a less traditional, yet more effective, form of XPS that allows samples to be analyzed at high pressures. NAP-XPS can be used to examine liquids, biological samples, porous materials, and other materials that are nearly impossible through classical XPS. We have examined Clinoptilolite, a type of Zeolite, by Near-Ambient Pressure XPS and fit O1s, Ca2p, C1s, K2p, Al2s, Al2p, Si2p, and Si2s narrow scans, and extended valence band spectrum of clinoptilolite that would be difficult to examine by conventional XPS. We also examined cuttlebone by NAP-XPS and show survey scans of Ca2p, C1s, O1s, and N1s. It is important to study Zeolites due to their applications in catalysis, removal of waste gases, water and soil treatments, etc. Cuttlebone also has a wide range of applications as a catalyst, a reinforcing filler for natural rubber, and it holds a similar structure to human bone, leading to great biological significance.
