Special Issue Information

Dear Colleagues,

This Special Issue on “Recent Progress in Nanomaterials for Sustainable Treatment of Heavy Metal Pollution in Wastewater and Soil” is dedicated to exploring the recent applications of novel sustainable nanotechnologies in the fields of wastewater, contaminated soil, and solid waste. This Special Issue particularly emphasizes sustainable waste management and new strategies in the treatment of heavy metals in wastewater, contaminated soil, and solid waste using nanomaterials.

This Special Issue comprehensively introduces the latest development achievements in this field, from aspects such as new adsorption materials and the recovery and secondary utilization of valuable resources, to environmental remediation and pilot-scale research. We sincerely invite researchers to submit research papers of academic value related to nanomaterials with unique insights, novel technologies, and excellent performance, or review papers that systematically summarize the cutting-edge aspects of emerging sustainable nanotechnology, to demonstrate the great potential of nanomaterials in the waste-treatment revolution.

Key thematic areas include the synthesis and characterization of highly selective nanomaterials tailored for specific waste-treatment applications, the assessment of nanomaterials in enhancing recycling efficiency, and the role of nanomaterials in the environmental remediation of waste-contaminated sites and water resources. In view of the complexity of real-world waste-treatment application scenarios, this Special Issue aims to provide valuable insights for future research in this field through the introduction of the current development of sustainable nanomaterial technologies.

Abstract
Heavy metal ions (HMIs) threaten ecosystems and human health due to their carcinogenicity, bioaccumulativity, and persistence, demanding highly sensitive, low-cost real-time detection. Electrochemical sensing technology has gained significant attention owing to its rapid response, high sensitivity, and low cost. Molybdenum disulfide (MoS2 [...] Read more.
Heavy metal ions (HMIs) threaten ecosystems and human health due to their carcinogenicity, bioaccumulativity, and persistence, demanding highly sensitive, low-cost real-time detection. Electrochemical sensing technology has gained significant attention owing to its rapid response, high sensitivity, and low cost. Molybdenum disulfide (MoS2), with its layered structure, tunable bandgap, and abundant edge active sites, demonstrates significant potential in the electrochemical detection of heavy metals. This review systematically summarizes the crystal structure characteristics of MoS2, various preparation strategies, and their mechanisms for regulating electrochemical sensing performance. It particularly explores the cooperative effects of MoS2 composites with other materials, which effectively enhance the sensitivity, selectivity, and detection limits of electrochemical sensors. Although MoS2-based materials have made significant progress in theoretical and applied research, practical challenges remain, including fabrication process optimization, interference from complex-matrix ions, slow trace-metal enrichment kinetics, and stability issues in flexible devices. Future work should focus on developing efficient, low-cost synthesis methods, enhancing interference resistance through microfluidic and biomimetic recognition technologies, optimizing composite designs, resolving interfacial reaction dynamics via in situ characterization, and establishing structure–property relationship models using machine learning, ultimately promoting practical applications in environmental monitoring, food safety, and biomedical fields.
