N-doped TiO2/carbon composites (N-TiO2/HTC) were synthesized by
hydrothermal carbonization using glucose, titanium isopropoxide and melamine, as
a carbon, titanium and nitrogen precursors, respectively. In order to achieve good
photocatalytic activity, different material samples were obtained by varying the
amount of melamine. Characterization of obtained composites was performed by
thermogravimetric analysis, scanning electron microscopy, X-ray diffraction, UVVis diffuse reflectance spectroscopy and Fourier transform infrared spectroscopy.
The photocatalytic activity of N-TiO2/HTC composites was examined via
photocatalytic degradation of methylene blue (MB) under UV and visible light, and
compared to the photocatalytic activity of undoped TiO2/HTC and commercial TiO2.
Variation of melamine amount, added in the precursor solution, induced slight
structural and morphological changes in N-TiO2/HTC composites. Although minor,
these changes caused different adsorption and photoc...atalytic characteristics of
obtained composites. It was found that the lowest addition of melamine raises the
adsorption capacity of composite material. Also, the increase in melamine
concentration in precursor solution increases the photocatalytic activity of N-doped
composites under both, UV and visible irradiation.
