摘要
Innovative and efficient electrocatalysts using selenide based composites are essential for electrochemical analyses and could significantly impact various modern technologies. This paper prepared a flake-like architecture comprising SnSe2 grafted N-doped carbon (NC) (SnSe2-NC) through a simple hydrothermal method and successfully applied the material for electrochemical sensing of carbendazim (CBZ). We investigated impacts from calcination temperature on prepared SnSe2 materials using various characterization methods, including XRD, XPS, BET, TGA, HR FE-SEM and FE-TEM. Nanocomposite electrochemical activity toward CBZ detection was ascribed to synergy between NC providing a conductive matrix and SnSe2 agglomeration providing large active surface area, superior conductivity, and abundant active surface sites. The fabricated sensor detected CBZ across a wide linear concentration range 0.002–139.38 μM under ideal conditions, with limit of detection = 0.67 nM. The propound sensor was effectively applied to detect CBZ in pure water and vegetable extracts, with reasonable recovery rates.
