摘　　要：通过水热和硒化法制备含镍的硒化铁(Ni-FeSe_(2))纳米材料,将其修饰在裸玻碳电极表面制成电化学传感器,应用于电化学检测.研究结果表明,Ni-FeSe_(2)对ONP具有优异的电化学响应,Ni含量的增加有利于提高检测灵敏度;10%Ni-FeSe_(2)修饰电极拥有较高的灵敏度和较低的检出限.Nickel doped iron selenide(Ni-FeSe_(2))nanomaterials were prepared by hydrothermal synthesis and thermally induced selenidation.The Ni-FeSe_(2)were modified on the surface of bare glassy carbon electrode to make an electrochemical sensor,which was applied to the electrochemical detection.The results shows that the Ni-FeSe_(2)exhibits excellent electrochemical response to ONP,and an increase in Ni content is beneficial for improving detection sensitivity.The 10%Ni-FeSe_(2)modified electrode obtains high sensitivity and lower detection limit.
