Abstract:A novel non-enzymatic nitrite sensor was fabricated by immobilizing MnOOH-PANI nanocomposites on a gold electrode (Au electrode). The morphology and composition of the nanocomposites were investigated by transmission electron microscopy (TEM) and Fourier transform infrared spectrum (FTIR). The electrochemical results showed that the sensor possessed excellent electrocatalytic ability for 2 NOoxidation. The sensor displayed a linear range from 3.0 μmol•L 1 to 76.0 mmol•L 1 with a detection limit of 0.9 μmol•L… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
