Abstract
In this study, non‐stoichiometric molybdenum oxide/prussian blue nanocomposites (MoO 3−x /PB NCs) were synthesized via a simple one‐pot method. The MoO 3−x /PB NCs can catalyze the conversion of dissolved oxygen into reactive oxygen species (ROS), generating chemiluminescence (CL) without additional oxidants. Meanwhile, compared with the original alkaline luminol solutions, it significantly enhances the CL signal, with an increase of over 1000‐fold. Utilizing the CL intensity‐quenching capability of HQ, a highly sensitive CL sensor has been developed. The linear range was 10–500 nmol·L −1 and the detection limit (LOD) was 1 nmol·L −1 , along with excellent selectivity and anti‐interference capability. At the same time, this study not only provided a new strategy for detecting HQ in lake and tap water but also expanded the application potential of MoO 3−x /PB NCs in CL analysis.Keywords
