Special Issue Information

Dear Colleagues,

In the last few decades, many studies have demonstrated that nanoparticles represent a versatile system that is widely used throughout scientific research in numerous applications within a number of different fields. Nanoscale functional materials have been explored in terms of their excellent mechanical properties, electrical properties, magnetic properties, optical properties, sensitivity, catalysis, and photoactivity.

This Special Issue aims to collect recent progress and developments in the design and synthesis of highly functional, nanostructured photocatalysts with enhanced properties. Furthermore, the mechanisms of photocatalytic degradation of organic pollutants and the processing–structure–property relationships are of great interest to this Special Issue.

In this work, new results concerning the potential of mixtures based on nitrogen doped titanium dioxide (TiO2:N) and carbon nanotubes (CNTs) as possible catalyst candidates for the rhodamine B (RhB) UV photodegradation are reported. The RhB photodegradation was evaluated by UV–VIS absorption spectroscopy using samples of TiO2:N and CNTs of the type of single-walled carbon nanotubes (SWNTs), double-wall carbon nanotubes (DWNTs), multi-wall carbon nanotubes (MWNTs), and single-walled carbon nanotubes functionalized with carboxyl groups (SWNT-COOH) having various concentrations of CNTs. The best photocatalytic performance was obtained for sample containing TiO2:N and 2.5 wt.% SWNTs-COOH, when approx. 85% of dye removal was achieved after 300 min. of UV irradiation. The reaction kinetics of RhB aqueous solutions containing TiO2:N/CNT mixtures followed a complex first-order kinetic model. The TiO2:N/CNTs catalyst induced higher photodegradation efficiency of RhB than TiO2:N due to the presence of CNTs, which act as adsorbent and dispersing agent and capture the photogenerated electrons of TiO2:N hindering the electron–hole recombination.
