About this Research Topic
The design and synthesis of nano-architected materials can lead to novel adsorbents of unique and essential physicochemical properties and remediation efficiency, usually not observed in their bulky counterparts. The main reason behind this is linked to an elevated number of atoms/groups, and as a result of the active sites, in the material’s surface in comparison to materials bulk. Consequently, many areas, such as electronics, photonics, remediation, and catalysis, have benefited from the innovative nanomaterials exploration, hence further development of new or/and modification of nanostructured materials is an open field of research. Following this trend, water treatment is an ever-growing area where nanostructured adsorbents/catalysts are assumed as prosperous candidates. Nanomaterials from different classes can be used in water remediation, for example, polymers, biopolymers, metallic, and semiconductor oxides nanoparticles. These nanomaterials can be used to decontaminate the water from different types of pollutants, such as dyes, pharmaceutical and cosmetic products, drug molecules, pathogens, industrial, and residential wastes. Background The need for clean water is a constant problem worldwide, which brings on the surface the necessity to seek affordable and sustainable materials and methods for water purification. Nanomaterials are assumed as promising candidates towards this direction, since their nanoscaled nature leads to important properties conferred by their nano-size and high active surface area. In this sense, this Research Topic welcomes the submission of nanostructured materials of different categories, such as polymers, nanoparticles, metal-organic frameworks and biomass-derived materials.
The goal of this Research Topic is to highlight research focusing on the synthesis and utilization of nanostructured materials for water purification applications. Potential nanostructured materials include, but are not limited to, MOFs, Engineered biochar, Carbon Quantum Dots (CQD), Graphene, Layered Double Hydroxides, Magnetic Materials, Aerogels, Cryogels and Xerogels, others.
We invite the submission of Original Research, Review, Mini Review, Perspective articles on themes including, but not limited to:
• materials’ synthesis routes and the key physicochemical characterizations
• nanomaterials that can be utilized in various water purification techniques, e.g. advanced oxidation, filtering, solid-liquid adsorption, or photocatalytic processes
• quantitative description and analysis of the efficiency of purification processes and comparison with previously reported data from the literature, whenever possible
Results from any scale, since the lab bench scale through pilot and industrial scales, are welcomed in this volume. Theoretical and computational papers will be also accepted as long as they have a clear connection with the experimental data describing the purification process. Finally, the novelty of the findings should be well defined.
