The role of nitrogen plasma surface treatment and TiO2 seeding onto carbon fibers on the microwave-assisted growth of radially aligned TiO2 nanowires

Radially aligned titanium dioxide (TiO2) nanowires were synthetized on nitrogen plasma-treated carbon fibers (CF) using a two-step microwave-assisted solvothermal method. The TiO2 synthesis consisted in seeding TiO2 nuclei on CF followed by TiO2 nanowire growth. To assess the role of the nitrogen plasma surface treatment and TiO2 seeding, CF and CF-TiO2 hybrids were analyzed by Raman spectroscopy, X-ray diffraction, scanning electron and atomic...
