An important goal in the preparation of highly active supported metal particles is the enhancement of the metal support interaction, providing a more stable catalyst, especially for liquid phase reactions as the leaching and reconstruction of the active phase causes deactivation. In this work, a covalent triazine framework (CTF) as support for Pd nanoparticles is compared to activated carbon (AC), the typical support used in liquid phase reactions. The results indicate that the presence of the N-heterocyclic moieties on the surface of the frameworks is beneficial for improving the stability of Pd nanoparticles during the liquid phase glycerol oxidation. Pd/CTF showed better activity and in particular better stability when compared to Pd supported on activated carbon (AC).
在制备高活性负载金属颗粒的过程中，一个重要的目标是增强金属-载体相互作用，提供更稳定的催化剂，特别是对于液相反应，因为活性相的浸出和重构会导致失活。在这项工作中，将共价三嗪骨架（CTF）作为 Pd 纳米粒子的载体与在液相反应中常用的活性炭（AC）进行了比较。结果表明，骨架表面的 N 杂环基团的存在有利于提高 Pd 纳米粒子在液相甘油氧化过程中的稳定性。与负载在活性炭（AC）上的 Pd 相比，Pd/CTF 表现出更好的活性，特别是更好的稳定性。
