Coupling of Nd doping and oxygen-rich vacancy in CoMoO₄@NiMoO₄ nanoflowers toward advanced supercapacitors and photocatalytic degradation

Abstract

A novel strategy that utilizes rare earth element doping and structure-directing agents was employed to synthesize oxygen-deficient 0.8% Nd–CoMoO4@NiMoO4 nanoflowers. The product has excellent electrochemical and photocatalytic properties.

Study of Nd-NiMoO4 Nanocomposites Prepared by Sol–Gel Method and Their Capacitive Properties

“…Figure 9b shows the Nyquist diagram of the sample after the 1st and 3000th cycles. The curve in the diagram consists of high frequencies and low frequencies, with the high-frequency region representing the impedance of ions passing through the surface film of the electrode material and the low-frequency region representing the charge transfer impedance [20]. In general, the value of the horizontal axis represents R s , and its value can be read according to the intercept of the curve and the horizontal axis, so the Rs value of the 10,000th cycle and the first cycle are 5.89 Ω and 2.62 Ω, respectively, which proves that the Nd-NiMoO 4 material has good electrical conductivity.…”
