Cu5Zn8@SiO2/NC derived from Cu/ZIF-8 as efficient electrochemical sensor for environmental pollutant detection in water bodies New J. Chem. (IF 3.3) Pub Date : 2024-04-07 Zihao Yu, Jingshuai Chen, Xing-Pei Liu, Chang-Jie Mao, Bao-Kang Jin
Sensitive detection of toxic substances in drinking water is always a difficult problem in electrochemical work. This paper presents a new electrode enhanced with nanomaterials for the sensitive detection of nitrobenzene (NB). A bimetallic Cu5Zn8 alloy generated from copper-zeolitic imidazole framework (Cu/ZIF-8) was created. And based on this, we synthesized Cu5Zn8@SiO2/nitrogen-doped carbon (NC)
