The renewable resource as a major feedstock to prepare porous carbon has showed many advantages compared to fossil-based materials. This study proposes a new strategy to synthesize palladium nanoparticles (Pd NPs)-supported porous carbon, utilizing both the chemical reactivity and the carbon-rich 3D network of lignin. The Pd NPs-supported porous carbons were prepared in one-pot synthesis, with Pd(NH)Cl as precursor, lignin as reducing and stabilizing agents of Pd NPs, nano SiO as hard-template, followed by carbonization and removal of the template. The results reveal a positive effect of Pd precursor dosage on the development and excellent texture of the Pd NPs-supported porous carbon. Accordingly, the synthesized porous carbon was proved to have large micropore volume and good micro-mesopore porous structure, revealing it a promising hydrogen adsorbent.
与基于化石的材料相比，可再生资源作为主要原料来制备多孔碳具有许多优势。本研究提出了一种利用木质素的化学活性和富碳 3D 网络来合成负载钯纳米粒子（Pd NPs）的多孔碳的新策略。Pd NPs 负载的多孔碳通过一锅法合成，以 Pd(NH)Cl 为前驱体，木质素为 Pd NPs 的还原剂和稳定剂，纳米 SiO 为硬模板，然后进行碳化和模板去除。结果表明，Pd 前驱体用量对 Pd NPs 负载的多孔碳的发展和优异的结构具有积极影响。因此，所合成的多孔碳具有大的微孔体积和良好的微孔-介孔多孔结构，表明其是一种很有前途的氢气吸附剂。
