[email protected] prepared by a facile pyrolysis method was used as the support of Pd catalyst for the hydrogenation of 4-carboxybenzaldehyde. The structure of Pd/[email protected] was characterized by N₂ adsorption-desorption, ICP-OES, SEM, HRTEM and XPS. The Pd/[email protected] catalyst showed superior activity compared with Pd/SiC due to its hierarchically mesoporous and microporous structure and the synergistic effect between Pd and N-doped carbon layer. In addition, Pd/[email protected] also exhibited a good durability under high temperature and high pressure H₂, which was attributed to its highly dispersed Pd nanoparticles stabilized by the N-doped carbon structure.

通过简便的热解方法制备的[受电子邮件保护的]用作Pd催化剂的载体，用于氢化4-羧基苯甲醛。通过N ₂吸附-解吸，ICP-OES，SEM，HRTEM和XPS对Pd / [受电子邮件保护的]结构进行了表征。与Pd / SiC相比，Pd / [受电子邮件保护的]催化剂表现出优越的活性，这是因为其具有分层的介孔和微孔结构以及Pd和N掺杂碳层之间的协同作用。另外，Pd / [受电子邮件保护]在高温高压H ₂下也表现出良好的耐久性，这归因于其高度分散的Pd纳米颗粒通过N掺杂的碳结构得以稳定。
