“…The high ratio of 0.45 indicates that ah igh amount of oxygen vacancies have been formed. Three peaks centered at 530.3, 531.8, and 533.1 eV in the O1ss pectrumc an be assigned to lattice oxygen, [19] chemisorbed oxygen by Ce 3 + in the form of ÀOH and CÀOs pecies or oxygen vacancies, [20] and oxygen bondedi nN iPhy structures, respectively (Figure 4b). [14] The ratio of chemisorbed oxygen accounted for 32 %o ft he surfaceo xygen species calculated from the peak areas in Ta ble S2,which was comparable to that of other NiÀCe based catalysts [18,21] and which further provedt he existence of ah igh concentrationo fo xygen vacancies.…”

“…The lattice parameter, crystallite size and lattice strain was summarized in Table . The Rietveld refinement of the pure ceria and manganese substituted ceria was done by using fullprof suite 2015 program software to calculate the lattice parameter . Table summarizes the lattice parameter, cell volume, reliability factor(R‐factor), Bragg's R‐factor and reduced chi‐square (χ 2 ).…”

“…Methods for achieving highly efficient oxidation of ethylbenzene in high-value added products, acetophenone and 1-phenylethanol, are very welcome in the chemical industry. Recently, the oxidation of ethylbenzene has been optimized to produce high yields of acetophenone [1][2][3][4][5][6][7][8][9][10]. During the production of high-value added products, however, there are many requirements that have to be met.…”

“…During the production of high-value added products, however, there are many requirements that have to be met. For example, the catalyst should be highly effective and recyclable [4], and should not produce toxic by-products, while the oxidant should be eco-friendly and sustainable [3,5]. Furthermore, the catalytic oxidation system should eliminate the use of solvents [5], the oxidation time should be as short as possible [5], and the potential for explosions of the oxidation reaction at high temperatures and pressures, even at room temperature, should be minimized [11].…”
