Instrument and Characteristics: The thermogravimetric analysis (TGA) was carried out in N2 on a TA instrument with a heating rate of 10 °C/min. The work functions of the modified cathode were investigated using a Kelvin probe (KP 6500 Digital Kelvin probe, McAllister Technical Services. Co., Ltd.). The samples were measured in a conditioned chamber where the O2 level is < 25 ppm. The actual work function of the samples can be obtained through the equation: WF= WF0+Δ WF Where WF is the sample work function, WF0 is standard gold probe work function (5.1 ev), and Δ WF is the work function gap between samples and standard gold.
