摘要：

Designing and synthesizing efficient and economical electro-sensing interface materials is essential for screening trace heavy metal ions in foods. In this study, we developed a multi-doped BNSP-C material with Zeolitic imidazolate framework-8 (ZIF-8) and non-metallic atoms (B, N, S, and P) for the simultaneous detection of the heavy metals Cd(II) and Pb(II) in complex food samples. The in situ doping of heteroatoms positively modifies the microstructure and current efficiency of the carbon precursor, creating additional active sites and defect...
