摘要

Developing a rapid sensing platform with effective pesticide degradation capabilities integrated into a single structure and realistic application is an imminent challenge to ensure sustainable agriculture and food safety. Here, we described establishment of a bifunctional nanoscale porphyrinic metal-organic framework (MOF) probe serving as a sensor for detection of trace nitenpyram and as a photocatalyst to facilitate the pesticide degradation. Based on the signal turned "on-off", the strong fluorescence of the probe was quenched by the target, leading to the sensing range from 0.05 to 10.0 mu g mL(-1) and a detection limit of 0.03 mu g mL(-1). Given the versatile design by which the porphyrin photosensitizers were isolated subtly in the MOF to avoid selfquenching, the probe was endowed with sustainable and efficient pesticide photodegradation activity with a degradation rate of similar to 95% for nitenpyram. Our work represents powerful all-in-one MOF-derived materials jointly for sensing and degrading pesticide residues in agricultural soils and other pesticide-contaminated environments.
