Application of Nanomaterials in Soil and Aquatic Environment Remediation

Dear Colleagues,

As human activity continues to degrade natural ecosystems, specifically soil and water resources, there is an increased demand for novel and sustainable approaches to environmental remediation. One of the most promising methods is nanotechnology, which offers advanced substances with unique properties, including large surface areas and tunable reactivity that make them excellent for treating a wide range of environmental contaminants.

This Special Issue brings together recent advancements in the application of nanomaterials (NMs) for the remediation of both terrestrial and aquatic media. Specific attention is given to the development and characterisation of sustainable NMs as catalysts and photocatalysts for the degradation of organic contaminants, especially emerging pollutants, as well as adsorbents for the removal of heavy metals. Studies that discover the degradation mechanisms are also emphasised, as they keep informed the development of safer and more effective NMs.

Sustainability underpins the whole issue. It assists the green synthesis of NMs, aiming to reduce environmental impacts while improving practical performance. In addition, comprehensive characterisation of NMs is encouraged to confirm reproducibility and environmental compatibility. Case studies and pilot projects promote the shift from lab-scale to real-world application, offering insight into the implementation's practical, economic, and regulatory aspects.

Topics of interest include, but are not limited to, the following:

• Sustainable synthesis and development of NMs for environmental applications.
• Advanced characterisation of NMs and their environmental interactions.
• Catalytic, including photocatalytic, degradation mechanisms.
• Remediation approaches based on adsorption and redox reactions.
• Degradation pathways and transformation byproducts.
• Fate, transport, and long-term behaviour of NMs.
• Risk assessment, ecotoxicology, and regulatory challenges.
• Field-scale applications and real-world case studies.
• Techno-economic and sustainability assessment of NMs-based technology.

This Special Issue will encourage the development of nanotechnologies in soil and water treatment for a sustainable future, and we look forward to your valuable contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
