Figure 3. (A) X-ray diffraction patterns of the QWF electrodes support (10°-70°), (B) Raman spectroscopy of QWF electrodes support, (C) TGA curves of CNT quantity of C-QWF-600, C-QWF-700; C 1s XPS spectra of (D) P-QWF, (E) N-QWF, and (F) C-QWF-700. QWF: Quartz woven fabric; TGA: thermogravimetric analysis; CNT: carbon nanotube; XPS: X-ray photoelectron spectroscopy; P-QWF: pristine QWF; N-QWF: Ni-coated QWF; C-QWF: CNT-coated QWF.
