摘　　要：以Cu(acac)2为金属有机铜前体,层状MgO为载体,采用金属有机化学气相沉积方法(MOCVD)制备了Cu/MgO催化剂,并通过X射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、场发射扫描电镜(FE-SEM)、透射电子显微镜(TEM)和N_2物理吸附等方法对Cu/MgO催化剂结构进行表征。结果表明,有机铜前体沉积在了MgO上,并且在沉积后,载体MgO的晶体结构仍然保留完整。利用生物质平台分子γ-戊内酯加氢反应来评价Cu/MgO催化剂的催化性能。研究表明,在473 K和10 MPa反应条件下,18%Cu/MgO催化剂表现出优异的催化活性(90.5%)和1,4-戊二醇选择性(94.4%),且催化剂循环三次,催化活性没有显著降低。The laminar MgO with high specific area and the organometallic precursor Cu （ acac） 2 were used for the successful synthesis of Cu/MgO catalysts by metal-organic chemical vapor deposition （ MOCVD） method. The copper supported on MgO catalysts were characterized by means of X-ray diffraction, Fourier-transform infrared （ FT-IR） spectroscopy, field emission scanning electron microscopy （ FE-SEM）, transmission electron microscopy （ TEM） and N2 -physisorption. Characterization results indicated that the organic precursor was successfully deposited onto MgO and the crystal structure of MgO remained intact after deposition. The hydrogenation of γ -valerolactone （γ -GVL） was employed to evaluate the catalytic performance of the Cu/MgO catalysts. It was found that the 18% Cu/MgO catalyst exhibited excellent catalytic activity （90. 5% ） and selectivity （94. 4% ） for 1,4-PDO at 473 K and 10 MPa, and the catalytic activity of Cu/MgO did not diminish significantly after cycling for three times.
