Abstract

In this study, we present a green synthesis approach for the fabrication of porous carbon supported palladium catalysts derived from Caesalpinia pods. The synthesis involves self-activation of Caesalpinia pods in a nitrogen atmosphere at various temperatures (600 °C, 800 °C, and 1000 °C) to produce porous carbon nanoparticles. Among the synthesized carbon materials, the sample CP-CNS/10 synthesized at 1000 °C exhibited the highest surface area of 793 m²/g with an average pore size diameter of 1.8 nm. The resulting porous carbon material served as an efficient support for palladium nanoparticles, with a low metal loading of about 0.2 mol% Pd for the reaction. This catalyst demonstrated excellent performance in the reduction of nitroarenes to their corresponding aromatic amines. The successful incorporation of approximately 4.5% Pd during the deposition process highlights the potential of the porous carbon supported palladium catalyst synthesized at 1000 °C for a sustainable and efficient heterogeneous catalyst for the reduction of nitroarenes.

生物废弃物衍生多孔碳支撑钯的合成与表征：作为硝基烯烃还原异相催化剂的系统研究

在本研究中，我们提出了一种利用皂荚制造多孔碳支撑钯催化剂的绿色合成方法。合成过程包括在不同温度（600 °C、800 °C和1000 °C）的氮气环境中对皂荚进行自活化，生成多孔碳纳米颗粒。在合成的碳材料中，在 1000 °C 下合成的 CP-CNS/10 样品的表面积最大，达到 793 m2/g，平均孔径为 1.8 nm。生成的多孔碳材料可作为钯纳米颗粒的有效载体，在反应中的钯金属负载量较低，约为 0.2 摩尔%。这种催化剂在将硝基烯烃还原为相应的芳香胺方面表现出卓越的性能。在沉积过程中成功加入了约 4.5% 的钯，这突出表明在 1000 ℃ 下合成的多孔碳支撑钯催化剂具有潜力成为硝基烯烃还原反应中可持续的高效异相催化剂。
