A Oxidation currents of 1-naphthol at different concentrations measured with Ti3C2Tx MXene modified electrode; B Absorbancy at 387.5 nm of 1-naphthol solution (curve a), mixture of 1-naphthol and hydrogen peroxide (curve b), mixture of 1-naphthol, hydrogen peroxide and Ti3C2Tx MXene (curve c), respectively. C The Faradic currents measured by electrode modified with Ti3C2Tx MXene at different concentrations in solution containing 7.0 mM 1-naphthol. D Charge density difference of the "lying-down" adsorption mode. Yellow and blue represent charge accumulation and depletion (isovalue: 0.005 au)
