Special Issue Information

Dear Colleagues,

Nanomaterials have attracted attention because of their unique characteristics, which allow them to be extensively used in numerous applications. Water treatment is an important concern in the environmental field. Nanomaterials in water treatment have been studied for many years with many applications. This Special Issue will present a collection of articles on nanomaterials and their application in wastewater treatment. This Special Issue includes, but is not limited to, the following potential topics:

  • The preparation, synthesis, and improvement of environmentally friendly nanomaterials applicated in water treatment;
  • Nanomaterials enhancing pollutant degradation in water treatment;
  • Recent advances in nanomaterials and nanotechnologies in wastewater treatment;
  • Evaluations of the application of nanomaterials in water treatment, including possible risks;
  • New nanomaterials, new nanotechnologies, etc.

Original research articles, reviews, letters to the editor, and short communications are welcome. We look forward to receiving your contributions.

Antibiotic abuse, particularly the excessive use of tetracycline (TC), a drug with significant environmental risk, has gravely harmed natural water bodies and even posed danger to human health. In this study, a three-dimensional self-supported MoS2/MXene nanohybrid with an expanded layer spacing was synthesized via a facile one-step hydrothermal method and used to activate peroxydisulfate (PDS) for the complete degradation of TC. The results showed that a stronger •OH signal was detected in the aqueous solution containing MoS2/MXene, demonstrating a superior PDS activation effect compared to MoS2 or Ti3C2TX MXene alone. Under the conditions of a catalyst dosage of 0.4 g/L, a PDS concentration of 0.4 mM, and pH = 5.0, the MoS2/MXene/PDS system was able to fully eliminate TC within one hour, which was probably due to the presence of several reactive oxygen species (ROS) (•OH, SO4•−, and O2•−) in the system. The high TC degradation efficiency could be maintained under the influence of various interfering ions and after five cycles, indicating that MoS2/MXene has good anti-interference and reusability performance. Furthermore, the possible degradation pathways were proposed by combining liquid chromatography–mass spectrometry (LC-MS) data and other findings, and the mechanism of the MoS2/MXene/PDS system on the degradation process of TC was elucidated by deducing the possible mechanism of ROS generation in the reaction process. All of these findings suggest that the MoS2/MXene composite catalyst has strong antibiotic removal capabilities with a wide range of application prospects. Full article
