چکیده انگلیسی
A non-enzymatic photoelectrochemical (PEC) biosensing platform for hydrogen peroxide (H2O2) detection based on highly conductive TiC/C core–shell nanofiber electrode decorated with WO3 nanowhiskers (WO3@TiC/C) is described. The electrode exhibits excellent visible-light induced photoelectrochemical activity as well as hydrophilic properties. Good photoelectrochemical (EC) biosensing properties with a H2O2 detection limit of 3 × 10−9 M (S/N = 3) and sensitivity of 386 μA mM−1 cm−2 are achieved. The stability, selectivity and anti-interference performance toward common inorganic salts and organic acids are also investigated and the results provide insights to non-enzymatic PEC H2O2 sensing.
