Special Issue Information
Dear Colleagues,
Soil and water contamination mainly results from improper discharge of toxic metals and emerging pollutants such as persistent organic pollutants, endocrine disrupting compounds, antibiotics, microplastics, etc. Metal oxide-based nanomaterials (MONMs), such as nanosized Fe oxide, MnO2, or their modified oxides, provide high surface area and specific affinity for various environmental remediation processes. The utilization of MONMs has received considerable attention due to their unique properties, including their extremely small size and surface modifiability. MONMs degrade emerging pollutants and immobilize inorganic toxic metals via photocatalysis, adsorption, redox, and electro-Fenton reactions. However, there are also some limitations (agglomeration, low photocatalytic activity, and difficult separation) for the practical environmental application of MONMs. Therefore, great efforts need to be made to fabricate novel multi-functional metal oxide-based nanomaterials to overcome those limitations and clarify the interaction mechanism between pristine and modified MONMs and different environmental contaminants.
This Special Issue aims to demonstrate the recent research advances on metal oxide-based nanomaterial remediation of contaminated soil and water. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:
- Metal oxide-based nanomaterial for soil and water remediation, including the preparation methodology, performance, and reaction mechanisms with contaminants of state-of-the-art metal oxide-based nanoparticles (e.g., Al2O3, TiO2, Fe oxides, MnO2, etc.).
- Modification technology of metal oxide-based nanomaterials for the enhancement of efficiency of environmental remediation, including bimetal doping, solid material as support (carbon material, clay minerals, hydrogel, chitosan, etc.), and surface modifications (silane, amines, thiols, carboxylic acids, etc.).
- The impact of metal oxide-based nanomaterials on the geochemical behavior of pollutants in the environment, especially soil and its remediation mechanisms.
- The adverse aspects, environmental risk, toxicology of metal oxide-based nanomaterials on plants, animals, microorganisms, enzyme activity, and ecosystems.
We look forward to receiving your contributions.
