摘要: A facile chemical solution deposition via two-step spin coating technique was used to fabricate nano-particulate novel Sn doped Co3O4 thin film for glucose sensor and fuel cell applications. Substitution of into host lattice lead a remarkable increase in the electrocatalytic activity electrode material. Film thickness played significant role enhancing charge transferability as observed from electrochemical impedance spectroscopy (EIS). The best exhibited two wide linear response ranges (2μM up ∼ 0.5 mM 0.6 mM ∼5.5 mM respectively) with sensitivities 921 265 μAcm−2mM−1 respectively low limit detection 100 nM (S/N=3). very selective towards presence various interference showed long term stability. Moreover, developed modified could generate one electron current nonenzymatic setup at room temperature.
