This project aimed to evaluate the synthesis route influence in the structural, morphologic and photocatalytic properties of carbon xerogel/Nb2O5 composites. Infrared spectroscopy and X-ray diffractometry confirm the existence of niobium-based oxides in the composites, whereas the diffuse reflectance and energy dispersive spectroscopy prove the incorporation of the carbon xerogel. The XC-24Nb composite presented the best photocatalytical response, as it presented higher crystallinity, high surface area and superior carbon xerogel incorporation. The XC-24Nb carb was the least effective material, probably due to its considerably inferior surface area. The degradation of methylene blue is controlled by electrons and electron vacancies. (AU)
