Abstract

Due to the serious pollution issue caused by 4-nitrophenol (4-NP), it is of great importance to design effective catalysts for its reduction. Here, a novel and simple strategy was developed for the synthesis of carbon dot-decorated gold nanoparticles (AuNPs/CDs) the carbonization of organic ligands on AuNPs at room temperature. The enhanced adsorption of 4-NP on CDs π-π stacking interactions provided a high concentration of 4-NP near AuNPs, leading to a more effective reduction of 4-NP.

摘要

由于4-硝基苯酚（4-NP）造成的严重污染问题，设计用于其还原的有效催化剂具有重要意义。在此，开发了一种新颖且简单的策略来合成碳点修饰的金纳米颗粒（AuNPs/CDs），即在室温下使AuNPs上的有机配体碳化。CDs上4-NP通过π-π堆积相互作用增强的吸附作用在AuNPs附近提供了高浓度的4-NP，从而导致4-NP更有效的还原。
