Rapid Discrimination of Adsorbed Oxygen and Lattice Oxygen in Catalysts by the Cataluminescence Method

open access: yesAnalytical Chemistry, 2022
Adsorbed oxygen and lattice oxygen are crucial parameters for catalyst characterization and catalytic oxidation mechanism. Therefore, rapid discrimination of adsorbed oxygen and lattice oxygen is highly desired. Herein, a direct correlation between cataluminescence (CTL) kinetic curve and oxygen species was discovered. The adsorbed oxygen-catalyzed CTL

Phase behaviour of oxygen adsorbed on graphite

open access: yesFluid Phase Equilibria, 1997
Molecular dynamics simulations are performed to investigate the physical adsorption of oxygen on graphite at 15 to 300 K with coverages from 0.192 to 2 monolayers. Below 25 K, the adsorbed molecules have translational ordering and are in a solid state.

Studies of molecular oxygen adsorbed on Cu surfaces

open access: yesSurface Science, 1986
Molecular oxygen adsorbed on (110) and polycrystalline Cu surfaces has been investigated by UPS, XPS, AES, HREELS and LEED. Molecularly adsorbed $O_2$ on the (110) surface shows the characteristic three-peak HeII spectrum due to $\pi_g$, $\pi_u$ and $\sigma_g$ orbitals, accompanied by an O-O stretching frequency at 660 $cm^{-1}$. On the polycrystalline
