N-doped carbon possesses the advantages of electronic modification and immobilization of metal nanoparticles. Hence, N-doped carbon-based metal catalysts have received extensive attention. This study prepared uniformly dispersed Ni nanoparticles (24.0 wt%) on porous N-doped carbon, which was fabricated via the high temperature pyrolysis of nitrogen-rich ZnNi MOFs with 1H-1,2,3-triazole as the ligand. The 1H-1,2,3-triazole as a high energy ligand could volatilize violently to form a N-doped macroporous carbon-based structure. Zn acted as a fence and prevented the accumulation of Ni during the pyrolysis of ZnNi MOFs. The synergistic effect from the abundant porous structure together with uniformly dispersed Ni nanoparticles proves the excellent catalytic activity toward the hydrogenation of dicyclopentadiene, showing 100% DCPD conversion and >99% THDCPD selectivity.

N掺杂碳具有电子修饰和固定金属纳米粒子的优点。因此，N掺杂的碳基金属催化剂受到了广泛的关注。该研究在多孔 N 掺杂碳上制备了均匀分散的 Ni 纳米粒子（24.0 wt%），该碳纳米粒子是通过以 1H-1,2,3-三唑为配体的富氮 ZnNi MOFs 的高温热解制备的。1H-1,2,3-三唑作为高能配体可以剧烈挥发形成N掺杂的大孔碳基结构。在 ZnNi MOFs 的热解过程中，Zn 起到了屏障的作用并阻止了 Ni 的积累。丰富的多孔结构与均匀分散的 Ni 纳米颗粒的协同作用证明了对双环戊二烯加氢的优异催化活性，显示 100% DCPD 转化率和 >
