摘要

本文以聚氧乙烯脂酰醚(ChEO10)和四氯金酸钠(III)二水合物(Na [AuCl4]-2H2O)为原料,在27℃条件下合成了超稳定的催化金纳米粒子(AuNPs)。在这里,通过AuCl4 -离子的络合和原位还原,还原ChEO10表面活性剂溶液支持了不同AuNPs的生成,其中ChEO10起着自还原和稳定的作用代理。这种方法被认为是简单和绿色的。用紫外-可见光谱法监测胶体AuNPs的发育情况。在前一部分中已经完成了合成AuNPs的完整表征。所得到的AuNPs在NaBH4的存在下,对甲基蓝(MB)降解为Leucomethylene Blue (LMB)具有优异的催化性能。我们进一步评论了这一令人兴奋和迅速发展的研究领域的挑战和未来方向。

Catalytic Degradation of Methylene Blue Using Gold Nanoparticles Capped by Polyoxyethylene Cholesteryl Ether
Simple spontaneous and eco-friendly green synthesis method for ultra-stable and catalytic gold nanoparticles (AuNPs) were synthesized through Polyoxyethylene cholesteryl ether (ChEO10) and sodium tetrachloroaurate (III) dihydrate (Na [AuCl4]-2H2O) were prepared at 27 °C (AuNPs were formed in < 2 h). Here the creation of distinct AuNPs is supported by reductive ChEO10 surfactant solution via complexation and in-situ reduction of AuCl4− ions in which ChEO10 acts as self-reducing and stabilising agent. This method is considered as simple and green. The positive development of colloidal AuNPs was monitored by simple UV-Vis spectroscopy. The complete characterization of synthesizing AuNPs was done in the previous part. The resulting AuNPs reveal outstanding catalytic properties for degradation of Methyl Blue (MB) to Leucomethylene blue (LMB) in the presence of NaBH4. We further comment on challenges and future direction of this exciting and rapidly expanding area of research.
