Recent advances in cataluminescence-based optical sensing systems.
Cataluminescence (CTL) is a specific chemiluminescence (CL) occurring on the surface of solid catalysts during heterogeneous catalytic oxidation reactions, and it is still a young technique compared to conventional CL. In recent years, CTL-based sensors have been widely used in the detection of various analytes. We have witnessed many developments in CTL-based sensing systems for the enhancement of sensitivity or selectivity. This review provides a thorough introduction to the history and development of CTL-based sensing systems. We have briefly discussed the working principles for CTL systems and related the influencing factors first. The development of CTL based on these factors and instruments has been subsequently introduced. Several excellent CTL-based sensing systems have been discussed to highlight their practicality for the analysis of complicated environmental samples. Discussions of the challenges and future trends of CTL-based sensing systems have been provided in the end of this review.
