Abstract In the present study, silver nanoparticles embedded N/S doped carbon (AgNPs@NSC) was synthesized by hydrothermal treatment of silver polymer complex. The formation of Ag nanoparticles in the N/S doped carbon (NSC) was confirmed via UV–Visible, FTIR, XRD, BET, XPS, and TEM analysis. The synthesized AgNPs@NSC nanocomposite exhibits excellent catalytic activity for the reduction of 4-nitrophenol (4-NP) into 4-nitrophenol (4-AP) in the presence of NaBH4. The fabricated catalyst show excellent catalytic activities and take only 6 min for the reduction of 4-NP. Furthermore, the highly porosity of carbon retained good activity and stability after five cycles. The foregoing study clearly suggests that synthesis of AgNPs@NSC nanocomposite by this method is efficient towards the development of a newer and a novel catalyst.

嵌入 AgNPs 的 N/S 掺杂碳作为减少有毒有机污染物的高效催化剂

摘要 在本研究中,通过对银聚合物配合物进行水热处理,合成了嵌入 N/S 掺杂碳的银纳米粒子 (AgNPs@NSC)。通过紫外-可见光、FTIR、XRD、BET、XPS 和 TEM 分析证实了在 N/S 掺杂碳 (NSC) 中形成了 Ag 纳米粒子。合成的 AgNPs@NSC 纳米复合材料在 NaBH4 存在下对 4-硝基苯酚 (4-NP) 还原为 4-硝基苯酚 (4-AP) 表现出优异的催化活性。制备的催化剂显示出优异的催化活性,还原 4-NP 仅需 6 分钟。此外,高孔隙率的碳在五次循环后仍保持良好的活性和稳定性。上述研究清楚地表明,通过这种方法合成 AgNPs@NSC 纳米复合材料对于开发更新的催化剂是有效的。
