摘要
研制了一种基于石墨氮化碳(GCN)/Pb2+/聚吡咯（PPy）的高稳定性电化学发光（ECL）传感器，用于检测痕量铜离子。首次应用盐酸浸渍技术对PPy链进行重排。在最佳实验条件下，ECL强度随溶液中Cu2+浓度从10-12 M增加到10-6 M （1 pM至1 uM）呈线性增加，超低检出限（LOD）为10-12 M (1 pM) （S/N = 3）。此外，利用Vienna ab-initio模拟软件包（VASP）和高斯16分析了检测对复合纳米材料局域态的影响。
Construction and mechanism analysis of an ultra-sensitive GCN/Pb2+/PPy heterojunction electrochemiluminescent sensor for detecting Cu(ii)†
A highly stable electrochemiluminescent (ECL) sensor based on graphitic carbon nitride (GCN)/Pb2+/polypyrrole (PPy) was developed to detect trace copper ions. The hydrochloric acid immersion technique was applied to rearrange PPy chains for the first time. Under optimal experimental conditions, the ECL intensity increased linearly with the increase of Cu2+ concentration in solution from 10−12 M to 10−6 M (1 pM to 1 μM), with a super low limit of detection (LOD) of 10−12 M (1 pM) (S/N = 3). Additionally, the impact of detection on the localized states of the composite nanomaterial was revealed by applying Vienna ab initio Simulation Package (VASP) and Gaussian 16.
