基于AgCl诱导的AuAg合金空心纳米立方体的催化性能研究

Study on the Catalytic Performance of AgCl Induced AuAg Alloy Hollow Nanoscubes

基于氯化银(AgCl)为模板,加入适量氯金酸(HAuCl4)和抗坏血酸(AA)简便地制备了平均粒径约为112nm的金银合金空心纳米立方体(AuAg HNCs)。由于AuAg HNCs具有空心多孔的结构特征,通过紫外-可见光谱(UV-Vis)探讨了其在室温下对有机污染物4-硝基苯酚(4-NP)的催化还原过程。实验结果表明,AuAg HNCs展现了优异的催化活性,可用于水污染物的去除和环境修复等方面。

Gold-silver alloy hollow nanocubes(AuAg HNCs)with an average particle size of about 112nm were facilely prepared based on silver chloride(AgCl)as a template by adding appropriate amounts of chloroauric acid(HAuCl_(4))and ascorbic acid(AA).Due to the hollow porous structural characteristics of AuAg HNCs,their catalytic reduction process of organic pollutant 4-nitrophenol(4-NP)at room temperature was explored by ultraviolet-Visible spectroscopy(UV-Vis).The experimental results showed that AuAg HNCs exhibited excellent catalytic activity and could be used for the removal of water pollutants and environmental remediation.
