Electrochemical insights into manganese-cobalt doped α-Fe₂O₃ nanomaterial for cholesterol detection: a comparative approach.

ABSTRACT: Herein, a self-assembled hierarchical structure of hematite (α-Fe₂O₃) was synthesized via a one-pot hydrothermal method. Subsequently, the nanomaterial was doped to obtain M _x Fe_2-x O₃ (M = Mn-Co; x = 0.01, 0.05, and 0.1) at precise concentrations. An electrode was fabricated by coating the resulting nanocomposite onto a nickel foam (NF) substrate. Electrochemical characterization demonstrated the excellent performance of cobalt-doped α-Fe₂O₃, among which Co_0.05Fe_0.95O₃ (CF5) exhibited a superior performance, showing a two-fold increase in sensitivity of 1364.2 μA mM^-1 cm^-2 (±0.03, n = 3) in 0.5 M KOH, a limit of detection (L
