In this work, palladium nanoparticles, supported by polyaminals (Pd@PAN-NA), were synthesized via a reverse double solvent approach and used as a nano catalyst. The thermogravimetric and the elemental analysis revealed that the catalyst had good dispersity and improved thermal stability. The catalytic activity of the prepared Pd@PAN-NA catalyst was studied for a methylene blue chemical reaction in the presence of NaBH as a reducing agent. The effect of the catalyst dose, pH, and dye initial concentration were examined to optimize the chemical reduction conditions. The prepared catalyst Pd@PAN-NA removed 99.8% of methylene blue organic dye, indicating its potential effect for treating waste and contaminated water.
在本工作中,通过反向双溶剂法合成了由聚胺(Pd@PAN-NA)负载的钯纳米颗粒,并将其用作纳米催化剂。热重分析和元素分析表明,该催化剂具有良好的分散性和提高的热稳定性。在作为还原剂的硼氢化钠存在下,研究了制备的Pd@PAN-NA催化剂对亚甲基蓝化学反应的催化活性。考察了催化剂用量、pH值和染料初始浓度的影响,以优化化学还原条件。制备的Pd@PAN-NA催化剂去除了99.8%的亚甲基蓝有机染料,表明其在处理废水和受污染水方面的潜在作用。
