Co3O4/α-Fe2O3 catalyzed oxidative degradation of gaseous benzene: Preparation, characterization and its catalytic properties

Enhanced catalytic oxidation of toluene over amorphous cubic structured manganese oxide-based catalysts promoted by functionally designed Co–Fe nanowires

“…In addition, the binding energies of both Co 3+ and Co 2+ in the Mn/Co–Fe/NF catalysts shift to the higher binding energy range when compared those of the Co–Fe/NF catalyst, which should be contributed by the interaction between the Co–Fe NWs and the Mn species with the MnCO 3 cubic structure. 44…”

“…In addition, the binding energies of both Co 3+ and Co 2+ in the Mn/Co-Fe/NF catalysts shift to the higher binding energy range when compared those of the Co-Fe/NF catalyst, which should be contributed by the interaction between the Co-Fe NWs and the Mn species with the MnCO 3 cubic structure. 44 Fig. 5(b) displays the O 1s XPS spectra of the catalysts, which can be classically fitted into two peaks at 529.8 (O lat ), and 531.2 (O sur ), which can be attributed to the oxygen species of the lattice oxygen (O 2− ) and the surface adsorbed oxygen (O 2 − , O − or O 2 2− ), respectively.…”

Recent progress on catalysts for catalytic oxidation of volatile organic compounds: a review

“…Moreover, it has been reported that the interaction between mixed oxides could affect the catalytic behaviors of mixed metal oxide catalysts for VOC degradation. 291 For example, Wang et al 292 prepared a Cu x Mn y /Al 2 O 3 catalyst applied for toluene oxidation. The authors found that Cu–O–Mn species with strong interaction formed on the Al 2 O 3 surface significantly facilitated the toluene degradation efficiency.…”

Synthesis of glycine-mediated CuO–Fe2O3–MgO nanocomposites: Structural, optical, and antibacterial properties

“…[4][5][6][7] By combining different metal oxides, various properties of individuals could be improved and a new track of research for biological, optoelectronics, thermal, and electrical applications could open up. 5,[8][9][10] Adding a new phase to a composite material can alter its electronic properties. Metal oxide NCs can be prepared through several routes, like hydrothermal, 10 co-precipitation, 11 selfcombustion, 12 ultrasonic-assisted method, 13 etc.…”
