英文摘要	In this study, a series of Co-Ni-Al-layered double hydroxides (CoxNiyAl1-LDHs) was successfully prepared via a simple co-precipitation method with Na2CO3 and NaOH as the precipitants. After the calcination of the CoxNiyAl1-LDH precursors, the Co-Ni-Al-O mixed oxides were formed and used as highly efficient catalysts in the selective oxidation of ethylbenzene to acetophenone. The Ni addition to CoAlOx can induce the formation of interactions between Co-Ni species and affect the dispersion of metal active centers, thereby greatly influencing the catalytic performance. The typical Co2Ni1Al1Ox sample with a Co:Ni molar ratio of 2:1 exhibited the highest surface area (165 m2/g) and the best catalytic performance (80.0% ethylbenzene conversion and 88.9% acetophenone selectivity). The high catalytic efficiency was mainly attributed to the high-efficiency synergistic effect between the highly dispersed active center Co and the promoter Ni species. More importantly, the good recyclability and stability of the Co2Ni1Al1Ox catalyst made it more competitive.
