Morphology-Controlled Fabrication of Co3O4 Catalysts and Performance Towards Low Temperature CO Oxidation

A green strategy for the selective recovery of lithium and the synthesis of CoFe2O4 catalyst for CO oxidation from spent lithium-ion batteries

“…, O 2− ) to form CO 2 . 32,46,47 As shown in Fig. 5b, the spectra indicated that at a temperature of 50 °C, carbonates, carboxylates, and formate groups were formed on the surface of CoFe 2 O 4 -LIBs catalysts, with a band at 2300–2400 cm −1 corresponding to the CO 2 peak.…”

Revealing the intrinsic nature of Ni-, Mn-, and Y-doped CeO2 catalysts with positive, additive, and negative effects on CO oxidation using operando DRIFTS-MS

“…TMO catalysts are prepared using coprecipitation, 27 sol–gel, 28 hydrothermal, 29 and aerosol pyrolysis methods. 30 When using the aerosol pyrolysis method by controlling the kinds and concentrations of precursors, atomization power, pyrolysis temperature, and gas atmosphere, the as-prepared catalysts have benefits from the doping, nano-engineering, and interfacing.…”
