Fundamental Aspects of Rare Earth Oxides Affecting Direct NO Decomposition Catalysis

Abstract: The basic aspects of rare earth oxides (REOs) that affect their capacity for direct NO decomposition catalysis were investigated. A correlation between crystal structure and catalytic activity was found, which is related to the NO adsorption ability of the REOs. The crystal structure was the most important factor affecting direct NO decomposition over REOs, since the adsorption of NO was significantly dependent on

“…Furthermore, a shoulder at 1625 cm -1 corresponding to the bending mode of molecular water can be seen in this spectrum [32]. The peak at 1384 cm -1 in the spectra of Sm 2 O 3 and SmN-RGO nanocomposites is assigned to the adsorbed nitrosyl (N-O) - [25]. In the spectra of SmN-RGO nanocomposites, the band around 590 cm -1 can be assigned to the Sm-O vibration of the strong interaction between SmNs and RGO which can describe anchoring of nanoparticles on RGO.…”

“…Dissociation of NO on the surface often depends on surface temperature, surface coverage, crystal plane and the concentration of surface defects [3]. Tsujimoto [24] along with Hong et al [25] have recently demonstrated that control of the surface basicity of the catalyst is also important in terms of enhancing NO decomposition activity. An active catalyst should allow easy desorption of oxygen atoms from the catalyst surface, which is a very important reaction step.…”

“…2,15,17,18 On the other hand, numerous studies have been carried out on lanthanide oxides or in other words rare earth oxides (REOs), because of their extensive utilizations in fuel cells, heterogeneous catalysis, ion glass industries and electronics. [19][20][21][22][23][24] Some REOs are considered potential candidates toward pseudocapacitors due to their redox properties. 19,25 Strategic rare earth compounds due to their electronic, optical and electrochemical characteristics arising from the electron transitions within the 4f shells, different conformation states and empty sites in the crystallization mode have been utilized in different elds such as high-performance luminescent devices, biochemical applications, catalysts and supercapacitors.…”
