a–b TEM images recorded at room temperature and under 0 V and 200 V, respectively. The black parts on top left and bottom right are Pt electrodes. c–d TEM images recorded under 80 V and at room temperature and 250 °C, respectively. e The enlarged {110}, {111}, and {200} diffraction peaks under various temperature. The intensities were normalized. f Raman spectra measured under various temperature.
