WebThe CuO/Co 3 O 4 coaxial heterostructures were dispersed in ethanol and analyzed by TEM, as shown in Figures 3(c)–3(e). The CuO/Co 3 O 4 coaxial heterostructures are covered by numerous interconnected Co 3 O 4 nanoparticles with an average diameter of 10 nm. In the crystallography, both (220) planes with a lattice spacing of 0.285 nm and (111 ... WebCuO x /CeO 2 is emerging as an effective catalyst for CO oxidation due to its unique redox properties; however, its activity and stability still need to be enhanced compared with supported platinum group metals. Here, an approach is demonstrated to increase the CO oxidation performance and resistance to hydrocarbon inhibition through the K + …
