Titanium carbide (
TiC) is a very significant transition
metal carbide that displays excellent stability and electrical conductivity. The electrocatalytic activity of
TiC is similar to noble metals but is much less expensive. Herein,
carbon nanofibers (CNFs)-supported
TiC nanoparticles (NPs) film (
TiC/C) is prepared by electrospinning and carbothermal processes. Well-dispersed
TiC NPs are embedded tightly into the CNFs frameworks. The electrochemical oxidation of
pyrimethanil (PMT) at the
TiC/C-modified
electrode displays enhanced redox properties, and the
electrode surface is controlled simultaneously both by diffusion and adsorption processes. When
TiC/C is applied for PMT determination, the as-fabricated sensor shows good sensing performance, displaying a wide linear range (0.1⁻600 μM, R² = 0.998), low detection limit (33 nM, S/N = 3), and good reproducibility with satisfied anti-interference ability. In addition,
TiC/C shows long-term stability and good application in natural samples. The facile synthetic method with good sensing performance makes
TiC/C promising as novel
electrode materials to fabricate efficient sensors.
