A binder-free Ru@NiMoS electrode was engineered by in situ growth of two-dimensional NiMoS nanosheets on nickel foam. This process effectively promoted the electrostatic-driven aggregation of Ru(bpy) , harnessing the synergistic effect to enhance electrochemiluminescence (ECL) performance. The integration (Ru@NiMoS) achieved an impressive ECL efficiency of 70.1%, marking an impressive 36.9-fold enhancement over conventional Ru. Additionally, its ECL intensity was found to be remarkably 172.2 times greater than that of Ru. Within the Ru(bpy) /TPA system, NiMoS emerged as a pivotal electrochemical catalyst, markedly boosting both the oxygen evolution reaction and the generation of reactive intermediates. Leveraging these distinctive properties, a highly efficient ECL sensor for lidocaine detection was developed. This sensor exhibited a linear response within the concentration range of 1 nM to 1 μM and achieved a remarkably low detection limit of 0.22 nM, underlining its substantial potential for practical application.
通过在泡沫镍上原位生长二维NiMoS纳米片制备了一种无粘结剂的Ru@NiMoS电极。该过程有效地促进了Ru(bpy) 的静电驱动聚集，利用协同效应提高了电化学发光（ECL）性能。集成体（Ru@NiMoS）实现了70.1%的令人印象深刻的ECL效率，比传统Ru提高了36.9倍。此外，发现其ECL强度比Ru显著高172.2倍。在Ru(bpy)/TPA体系中，NiMoS成为关键的电化学催化剂，显著促进了析氧反应和活性中间体的生成。利用这些独特性能，开发了一种用于利多卡因检测的高效ECL传感器。该传感器在1 nM至1 μM的浓度范围内表现出线性响应，检测限低至0.22 nM，突出了其在实际应用中的巨大潜力。
