Special Issue Information

Dear Colleagues,

Given increasing industrialization, rising global populations, growing fuel demand, spiraling pollution, and global climate change, environmental challenges have garnered significant global attention in areas ranging from waste management to sustainable development. The development of effective and affordable materials for environmental remediation technologies is required to tackle complicated and interlinked environmental issues. Due to their high surface areas, tunable surface chemistry, and distinctive properties, 2D nanomaterials are highly important for environmental monitoring (e.g., chemical or bio-sensors), environmental remediation, and environmental energy. In this Special Issue, we highlight how 2D nanomaterials can play a significant role in addressing existing environmental problems.

This Special Issue considers the following topics:

  • Two-dimensional nanomaterials and their nanocomposites for water and wastewater treatment;
  • Two-dimensional nanomaterials and their nanocomposites for pollutant adsorption;
  • Two-dimensional nanomaterial-based photocatalysts for removing pollutants;
  • Two-dimensional nanomaterials and their nanocomposites for membrane separation, desalination, and deionization;
  • Two-dimensional nanomaterials and their nanocomposites for environmental pollutant sensing/detection, including electrochemical, fluorometric, colorimetric, electrochemiluminescent, photoelectrochemical, and field-effect transistor sensors;
  • Two-dimensional nanomaterials and their nanocomposites for the capture of CO2 and other gaseous molecules, as well as the catalytic conversion of CO2;
  • Two-dimensional nanomaterials and their nanocomposites for microbial treatment and electrochemical remediation;
  • Environmental risks of two-dimensional nanomaterials.

Nanomaterials can significantly improve the analytical performance of optical sensors for environmental pollutants. Two-dimensional (2D) molybdenum sulfide (MoS2) exhibits some unique physicochemical properties, such as strong light–matter interactions, bandgap tunability, and high carrier mobility, which are beneficial for constructing flexible optoelectronic devices. In this review, the principle and classification of 2D MoS2-based photodetectors (PDs) are introduced, followed by a discussion about the physicochemical properties of 2D MoS2, as well as the structure–property relationships of 2D MoS2-based photoactive materials for PDs to understand the modulation strategies for enhancing the photodetection performance. Furthermore, we discuss significant advances in the surface modification and functionalization of 2D MoS2 for developing high-performance PDs, particularly focusing on synthesis pathways, modification strategies, and underlying physiochemical mechanisms for enhanced photodetection capabilities. Finally, conclusions and research perspectives on resolving significant bottlenecks or remaining challenges are offered based on recent developments in 2D MoS2-based PDs. Full article
