Abstract |
Photodegradation of organic pollutants by oxide-based photocatalysts has gained increasing attention as a solution to environmental problems. Generally, the degradation of pollutants proceeds by reaction with reactive hydroxyl radicals, which are generated by the reaction of water molecules adsorbed onto the photocatalyst with photogenerated charge carriers in the photocatalyst. However, the fast recombination rate of photogenerated charge carriers limits the ability for enhanced catalytic efficiency of oxide based photocatalysts. The difficulty of separating and recycling these catalysts also hinders their practical application. In this study, we report on the preparation and photocatalytic properties of a RuO2–carbon nanotube (RuO2–CNT) nanocomposite, comprised of RuO2 nanoparticles deposited onto a thiolated CNT substrate by wet chemical methods. The RuO2–CNT nanocomposite was characterized by spectroscopic methods. The photocatalytic activity of the RuO2–CNT nanocomposite was evaluated using degradation of methylene blue (MB) under UV–vis light. |
