Abstract
- The low-temperature synthesis of the graphene oxide–wrapped perovskite-type strontium titanate nanocomposites (GO@SrTiO<subscript>3</subscript>-NC) is reported for the electrochemical sensing of organochlorine pesticide 2,4,6-trichlorophenol (TCP) detection. The as-prepared GO@SrTiO<subscript>3</subscript> nanocomposites provide a large surface area, excellent conductivity, and active sites, which are more favorable to the catalysis of TCP. The synergistic effect between the GO and the perovskite SrTiO<subscript>3</subscript> results in the extended working range of 0.01 to 1.47 and 1.47 to 434.4 μM with a very low detection limit of 3.21 nM towards TCP detection. Moreover, the prepared sensor possessed good selectivity and long-term stability. Finally, the practical applicability of the sensor was tested in environmental samples of river water and soil, exhibiting adequate recovery values. [ABSTRACT FROM AUTHOR]
