support, catalyse the C–C coupling (aldol) process. This supported bimetallic catalyst is also effective in utilizing hydrogen from the dehydrogenation reaction for the hydrogenation of 4-(4-methoxyphenyl)but-3-en-2-one to 4-(4-methoxyphenyl)butane-2-one via a hydrogen auto transfer route. These multifunctional catalysts were characterised using transmission electron microscopy, X-ray diffraction and
我们报告了使用多功能负载型AuPd纳米合金催化剂直接从4-甲氧基苄醇和丙酮进行一锅串联合成4-(4-甲氧基苯基)丁-2-酮。这种一锅法合成涉及C的脱氢,羟醛缩合和氢化。在这种负载型AuPd催化剂中,双金属位点催化脱氢和氢化步骤,并与载体一起催化C-C偶联(羟醛)过程。该担载的双金属催化剂还可以有效地利用脱氢反应中的氢通过以下方法将4-(4-甲氧基苯基)but-3-en-2-one氢化成4-(4-甲氧基苯基)丁烷-2-one 。氢气自动传输路线。使用透射电子显微镜,X射线衍射和X射线光电子能谱对这些多功能催化剂进行了表征。
