Photocatalytic oxidation of methanol using titanium dioxide/single-walled carbon nanotube composite
Titanium dioxide/single-walled carbon nanotube (TiO2 /SWNT) composites were prepared for photocatalytic applications. The composites were characterized using UV-visible and Raman spectroscopy, zeta-potential measurements, cyclic voltammetry coupled with a photoreactor, scanning electron microscopy,...
