The exploration of non-precious metal electrocatalyst with high performance for oxygen reduction reaction (ORR) is vital for widespread application of fuel cells. In this study, we presented a rational designed Fe, N-doped graphene nanoribbon/carbon nanotube composite (FeN-uCNT) based on partial longitudinally unzipped MWCNTs with abundant edge defects as a highly active catalyst for ORR. The obtained...
Mesoporous SnO 2 nanotubes are prepared by templating against carbon fibers through a facile solution approach followed by calcination at 800°C for 2h. The nanotubes are characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and nitrogen adsorption. The electrochemical performances as the...
