Abstract Novel thiol functionalized xylose hydrochar microspheres supported palladium nanoparticles (C–SH–Pd) were synthesized by gentle heating of palladium (II) acetate and thiol functionalized xylose hydrochar (C–SH) in ethanol. The as-prepared C–SH–Pd exhibited high catalytic activity towards Suzuki reactions with a yield of high up to 100%. Moreover, it could be reused for at least five times without heavily loss of the catalytic activity. The amount of palladium entrapped on C-SH microspheres was measured by AAS and found to be 1.42 mmol/g. Leaching studies showed that the filtrate contained less than 0.2 ppm Pd. Due to the superior catalytic performance and stability of the C–SH–Pd catalyst, it can be exploited in other cross coupling reactions in the long run. Graphic Abstract

锚定在硫醇官能化木糖水炭微球上的钯纳米颗粒：一种用于 Suzuki 交叉偶联反应的高效多相催化剂

摘要 通过在乙醇中温和加热乙酸钯 (II) 和硫醇官能化木糖氢化碳 (C-SH)，合成了新型硫醇官能化木糖氢化碳微球负载钯纳米粒子 (C-SH-Pd)。所制备的 C-SH-Pd 对 Suzuki 反应表现出很高的催化活性，产率高达 100%。此外，它可以重复使用至少五次而不会严重损失催化活性。用原子吸收光谱法测量 C-SH 微球上的钯含量，结果为 1.42 mmol/g。浸出研究表明滤液含有少于 0.2 ppm 的 Pd。由于C-SH-Pd催化剂优异的催化性能和稳定性，从长远来看，它可以用于其他交叉偶联反应。图形摘要
