Effects of Cu doping on electrochemical NOx removal by La0.8Sr0.2MnO3 perovskites

Ordered phase transformation and Cu doping effects in room-temperature ferromagnetic Sr3YCo4O10.5+δ

“…The XPS results confirm that the Cu 2+ ions predominantly occupy Co 3+ sites. In Figure 6E, the Cu 2+ signal (Cu2p 3/2 and Cu2p 1/2 are 934.07 and 953.87 eV for x = 0.2, 933.49 and 953.29 eV for x = 0.4, respectively) and its satellite peak (936.0-946.0 eV) in the Cu 2p spectral range are obvious (Wu et al, 2018;Li et al, 2022). The results show that in Sr 3 YCo 4−x Cu x O 10.5+δ , Cu ions exist in the oxidation state of +2 valence.…”

Selective detection of NO using the perovskite-type oxide LaMO3 (M = Cr, Mn, Fe, Co, and Ni) as the electrode material for yttrium-stabilized zirconia-based electrochemical sensors

“…32 Although the LaMO 3 is attributed to the rhombohedral space group, its primitive cells have a cubic structure. Therefore, as in several other studies, 1,2,33 for convenience, LaMO 3 based on a cubic structure was used for DFT calculations. It has been reported that this choice has little effect on the adsorption energies of similar LaMO 3 perovskites.…”

Catalytic oxidation of NO over MnO2 nanorods with different phase structures

“…The utilization of catalysts for the oxidation of NO represents an additional efficacious and extensively employed methodology. Transition metals, including manganese, cobalt, cerium, chromium, and copper, have been shown to be effective catalysts for NO oxidation [8][9][10][11][12] . Over the past few years, manganese-based catalysts have gained significant attention owing to their numerous advantages, which include high catalytic activity and environmental friendliness.…”
