摘要:
采用浸渍法在介孔碳(MC)上负载Pd制备Pd/MC催化剂。采用X线衍射仪(XRD)、比表面积仪(BET)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)及H2程序升温脱附法(H2-TPD)对Pd/MC进行表征。考察Pd/MC水相催化氧化苯甲醇制备苯甲醛的性能。结果表明:MC 具有良好的介孔结构及高比表面积; Pd纳米颗粒在MC表面高度分散并稳定; Pd/MC具有较高的氧化还原性。在优化反应条件苯甲醇 1 mmol、n(Pd)/n(苯甲醇)=0.001、水4 mL、反应温度80 ℃、反应时间12 h、常压O2下,苯甲醇转化率达到99.6%,苯甲醛选择性为100%。催化剂重复使用5次,催化剂活性基本不变。
Abstract:
The catalysts of Pd/MC were prepared by impregnation methods of Pd on mesoporous carbons(MC).The samples were characterized by X-ray diffraction(XRD),specific surface area(BET),scanning electron microscope(SEM),transmission electron microscope(TEM), and H2-temperature-programmed-desorption(H2-TPD).The catalytic performance of Pd/MC was investigated for aerobic oxidation of benzyl alcohol using water as a solvent.The result showed that MC had good mesoporous structure and high surface area.Pd nanoparticles were highly dispersed on MC surface and showed the stability.Pd/MC exhibited better redox performance.Results indicated that 99.6% conversion of benzyl alcohol and 100% selectivity to benzaldehyde were obtained with Pd/MC under the optimized reaction conditions of benzyl alcohol 1 mmol,n(Pd)/n(benzyl alcohol)=0.001,H2O 4 mL,80 ℃,12 h and O2 atmosphere.Pd/MC showed the catalytic stability for benzyl alcohol oxidation with five time reuses.
