Applications of nanomaterial-based chemiluminescence sensors in environmental analysis

More attention is being paid to the environmental analysis because of the increasingly serious environmental pollution. Due to the superiority of low interference, excellent sensitivity, rapidness, and simple construction, chemiluminescence (CL) has evolved into a powerful technique for pollution analysis. Recently, nanomaterials such as MOFs, BPQDs, CDs, MoS2, LDHs, and noble metal NPs, have been exploited to further amplify the CL radiation, owing to their wide surface area, unique photoelectric properties, and excellent reactivity. Much encouraging progress in environmental analysis utilizing nanomaterial-based CL has been made. However, a comprehensive summary concentrated on the application of nanomaterial-based CL for environmental analysis is still lacking. In this review, the recent advances of nanomaterial-based CL in environmental pollutant analysis for typical harmful substances are summarized during the last 5 years, including inorganic ions, ROS, antibiotics, and pesticides, etc. Ultimately, the key challenges and further prospects in this exciting area are also highlighted to promote the advancement of environmental analysis. •Main types and sensing principles of nanomaterials used in chemiluminescence systems are summarized.•Applications of nanomaterial-based chemiluminescence in environmental pollutant analysis are reviewed.•Key challenges and further prospects of this nanomaterial-based chemiluminescence are proposed.
