The catalytic properties of hydrotalcite‐based Cu/Zn/Al mixed oxides prepared by the incipient co‐precipitation method, in which various metals were doped through impregnation, were comparatively tested in the steam reforming of methanol (SRM). In addition, the catalysts were characterized in detail by a series of follow‐up surface techniques. Moreover, strong interaction and synergism between Ru and Cu species noticeably promoted methanol conversion and improved catalytic performance. Furthermore, an SRM reaction mechanism is proposed that rationalizes the relationship between copper dispersion on the surface and the size of the copper/oxygen interface where formed intermediates rearrange.

甲醇蒸汽重整中水滑石基Cu / Zn / Al催化剂上各种金属的研究

在甲醇蒸汽重整中，比较测试了通过共沉淀法制备的水滑石基Cu / Zn / Al混合氧化物的催化性能，该方法通过浸渍来掺杂各种金属。此外，通过一系列后续表面技术对催化剂进行了详细表征。此外，Ru和Cu物种之间的强相互作用和协同作用显着促进了甲醇的转化并改善了催化性能。此外，提出了一种SRM反应机理，该机理使表面上的铜分散与形成的中间体重排的铜/氧界面的尺寸之间的关系合理化。
