Nuclear Magnetic Resonance (NMR) Analysis of [Bmim]BF4/CH3CN Electrolyte Solution Before and After Electrocatalytic Reactions

///'Among them, Ws is the mass of tritium substitute in the NMR tube; Ax is the peak area of the sample; As is the peak area of the internal standard; E is the proton equivalent of the sample at that chemical shift, that is, the molecular weight of the sample divided by the number of protons in the functional group that generates the resonance peak; Es is the proton equivalent of the internal standard at that chemical shift. The NMR results before and after catalysis of the [Bmim]BF4/CH3CN electrolyte solution used for electrocatalysis are shown in Figure 2-3.///
