1金催化制备氯乙烯单体进展(英文)显示文摘本文综述了Au用于乙炔氢氯化反应的研究历史、最新研究进展及商业化进程.讨论了使用不同前驱体和添加第二金属助剂等方法对催化剂性能的改进,探讨了活性金物种的性质.尽管HgCl_2会导致环境污染等问题,但全球大量聚氯乙烯(PVC)的生产仍采用HgCl_2作为催化剂.由于中国计划未来几年内将不再使用Hg生产PVC,因此急需探索替代催化剂.数十年来人们普遍认为Au是该过程的最佳替代催化剂,这主要是因为与其他金属相比,金催化剂的选择性更高.Catherine J.Davies Peter J.Miedziak Gemma L.Brett Graham J.Hutchings 2016Chinese Journal of Catalysis2016,37,10:6

3The hydrogenation of levulinic acid to γ-valerolactone over Cu–ZrO2 catalysts prepared by a pH-gradient methodology显示文摘A novel pH gradient methodology was used to synthesise a series of Cu–ZrO2 catalysts containing different quantities of Cu and Zr.All of the catalysts were highly selective to the desired product,γ-valerolactone, and are considerably more stable than Cu–ZrO2 catalysts prepared by other co-precipitation methods for this reaction.Characterisation and further investigation of these catalysts by XRD, BET, SEM and XPS provided insight into the nature of the catalytic active site and the physicochemical properties that lead to catalyst stability.We consider the active site to be the interface between Cu/CuOxand ZrOx and that lattice Cu species assist with the dispersion of surface Cu through the promotion of a strong metal support interaction.This enhanced understanding of the active site and roles of lattice and surface Cu will assist with future catalyst design.As such, we conclude that the activity of Cu–ZrO2 catalysts in this reaction is dictated by the quantity of Cu–Zr interface sites.Igor Orlowski Mark Douthwaite Sarwat Iqbal James S.Hayward Thomas E.Davies Jonathan K.Bartley Peter J.Miedziak Jun Hirayama David J.Morgan David J.Willock Graham J.Hutchings 2019Journal of Energy Chemistry2019,28,9:0
