Abstract:
Electrochemiluminescence(ECL)refers to the process of luminescence triggered by high-energy electron transfer between intermediate products during the oxidation-reduction reaction on the electrode surface.In the co-reactants involved ECL process,the presence of co-reaction accelerators can effectively catalyze the decomposition of co-reactants,leading to the generation of abundant free radical intermediates,thereby significantly enhancing the ECL signals.This plays a critical role in constructing simple,sensitive,and efficient ECL sensing platforms.This review focused on the novel co-reaction accelerators developed in recent years.Based on different types of co-reaction accelerator materials,including single atom catalysts,metal-based nanomaterials,polymers and other materials,the ECL reaction process and signal enhancement mechanisms,as well as their relevant applications in constructing ECL sensing platforms,were elucidated.Furthermore,the current research challenges and development prospect of co-reaction accelerators were also discussed.
