Sketching a proper catalytic system with supplementary attributes, containing easy separation, wide surface area, supreme loading capacity, and fantastical electronic attributes, proposes an encouraging direction for efficiently using nanostructures for various applications. However, the capability to adjust the nano-measure bimetallic particles is an adjustment for attaining superb performance in the catalytic field. Herein, an environmentally benign approach was developed for immobilizing and anchoring Pd-Cu alloy nanoparticles on murexide (MX)-functionalized carbon nanotubes (CNTs). Afterward, the catalytic activity of Pd₂-Cu₃@MX/CNT was studied in synthesizing 2,3-dihydro quinazoline-4(1H)-ones and carbon–carbon coupling reactions at sustainable reaction conditions under ultrasound irradiation. The results demonstrated that high-affinity MX ligand and porous CNT structures than the adsorption of Pd–Cu had a unique designation in the high-range constancy of the alloy nanoparticles and following catalytic activity. In addition, ultrasound irradiation got electrons of Pd–Cu alloy nanoparticles agitated, constructing a synergic efficacy between Cu and Pd metals for synthesis and coupling reactions. Our study represents that the designed catalyst is green, recyclable, and most suitable, providing new intuition into in high-range constancy of bimetallic nanoparticles for broad applications.

钯铜合金在紫脲酸改性碳纳米管上的稳定和锚定作为优异的纳米催化剂：在偶联和合成反应中表现出色

勾勒出具有补充属性的适当催化系统，包括易于分离、宽表面积、最高的负载能力和奇妙的电子属性，为有效地将纳米结构用于各种应用提供了令人鼓舞的方向。然而，调整纳米级双金属粒子的能力是为了在催化领域获得优异性能而进行的调整。在此，开发了一种环境友好的方法，用于将 Pd-Cu 合金纳米颗粒固定和锚定在螺脲 (MX) 功能化碳纳米管 (CNT) 上。随后研究了Pd ₂ -Cu ₃ @MX/CNT在合成2,3-二氢喹唑啉-4(1 H)-酮和碳-碳偶联反应在超声波照射下可持续反应条件下的反应。结果表明，高亲和力MX配体和多孔CNT结构比Pd-Cu吸附在合金纳米颗粒的高范围稳定性和后续催化活性方面具有独特的设计。此外，超声波照射使Pd-Cu合金纳米颗粒的电子受到搅动，在Cu和Pd金属之间构建了合成和偶联反应的协同效应。我们的研究表明，设计的催化剂是绿色、可回收且最合适的，为双金属纳米粒子的广泛应用的高范围稳定性提供了新的直觉。
