| 概要 |
In this research, carbon-doped ZnO/N (Zinc Oxide/Nitrogen) with nanorod structures were successfully synthesized using hydrothermal method by varying the ammonia molarites (1 M; 3 M; and 5 M). In the ...preparation, carbon-doped ZnO/N was produced by reacting Zn(NO_3)_2•6H_2O; Urea; Citric Acid; and ammonia (NH_4OH) at 160 ℃ for 10 hours and calcinated at 600 ℃ for 2 hours as the carbonization process and marked as ZnO/N-C. The XRD analysis reveals that all of the samples' crystalline structures are almost hexagonal in shape, with crystalline sizes of 19.96 nm for ZnO/N-C (A-1M); 17.02 nm for ZnO/N-C (A-3M); and 25.11 nm for ZnO/N-C (A-5M). In the reverse hand, the images SEM results indicate that all of the sample morphology is nanorods, and the EDX test results confirm the chemical composition of all samples, which confirms that nitrogen and carbon were present. Electrochemical Impedance Spectroscopy (EIS) was used to assess the electrochemical characteristics to obtain the resistance coefficient transfer (R_<ct>) data. According to the EIS data analysis, the R_<ct> for the ZnO/N-C (A-1M), ZnO/N-C (A-3M), and ZnO/N-C (A-5M) samples are 339.8, 359.8, and 285.4 ohm, respectively. As a result, the sample that exhibits the lowest R_<ct> value will be a potential candidate for the most efficient of the electron transfer process.続きを見る
