Furthermore, a correlated study of –Z″ and M″ shows the charge-carrier relaxation behavior changes from ideal Debye type to non-Debye type with temperature rise in Fe, Cu–doped CeO2.doi:10.1002/pssa.202300349Manish Kumar Vishwakarma
Nanometer Cu-doped CeO2 (nano@Cu–CeO2) was synthesized by the method of precipitation. All catalysts were evaluated for the catalytic oxidation of CO, and the 3D@Cu–CeO2 catalyst exhibited the highest catalytic activity (complete conversion temperature T100 = 50 °C), which can be ...
Cu/CeO2nanorods (Cu/CeO2-R) and flower-like Cu/CeO2microspheres (Cu/CeO2-F) to systematically explore the structure-activity relationship in CO oxidation. Crucially, the effect of morphology, crystal size, Ce4+
respectively. The most employed TCOs at industrial scale—Sn-doped In2O3(ITO), Al-doped ZnO (AZO) and F-doped SnO2(FTO)—haven-type conductivity; among them, ITO stands out with electrical conductivity around 103S cm−1and transparency above 80% in the visible range [1,2]. N-type ...

Liu et al. demonstrated the good performance with a Cu/CeO2/doped graphene catalyst, but they needed the 250 W lamp illumination and Na2SiO3 reagent. CH3OH dehydrogenation for hydrogen (H2) currently perform through steam reforming over the heterogeneous CuO/ZnO/Al2O3 catalyst at 200–300...
we synthesized a series of Cu/CeO2 catalysts with different morphology and size, including Cu/ CeO2 nanospheres (Cu/CeO2-S), Cu/CeO2 nanoparticles (Cu/CeO2-P), Cu/CeO2 nanorods (Cu/CeO2-R) and flower-like Cu/CeO2 microspheres (Cu/CeO2-F) to systematically explore the structure-acti...
