Nanotechnology for the Removal of Gaseous and Liquid Phase Pollutants by Adsorption and Catalysis

About this Research Topic

The rapid development of the economy has brought convenience to society, but also several serious environmental issues. The consequences of water and air pollution caused by human activity force governments, industries and academia to seek efficient solutions and technologies in order to handle these environmental problems. Adsorption, catalysis, biological processes, and other technologies are the main methods currently used to remove most pollutants from the environment, such as heavy metals, dyes, antibiotics, volatile organic compounds (VOCs), CO and others.

Pollutants with different characteristics, and in various environments, may require different removal technologies. For example, in the case of heavy metal pollution in water, studies have shown that adsorption tends to achieve better results. It is found that both adsorption and photocatalysis can achieve good results for dye removal. Photocatalysis is also frequently used to address water contamination from antibiotics via degradation paths. Exploring these solutions in the nanoscale has led to the synthesis of a variety of nanostructures with environmental remediation applications.

The main goal of this Research Topic is to highlight the nanotechnologies used in order to degrade various liquid and gaseous pollutants efficiently, with low energy consumption and overall minimum environmental footprint.

We invite the submission of Original Research, Review, Mini-review and Perspective articles. The areas of focus may include, but are not limited to:
• Nanostructures for pollutant adsorption applications, including liquid phase (heavy metals, antibiotics, dyes, etc.) and gaseous (VOCs, NOx and CO) pollutants
• Nanostructures for catalytic oxidation of gaseous pollutants (mainly VOCs), including the exploration of its principle and the modification of catalysts
• Nanostructures for efficient photocatalytic degradation of liquid and gas phase pollutants (degradation principle, mechanisms and path)
• Preparation and modification of catalysts, along with the study of catalytical performance and potential; improvements on synthetic methods, the study of synthetic materials, the reduction of cost and time for synthesis (eg. by improving the catalytic conditions) observed improvements in material stability by optimizing the catalyst, are also welcome.


Keywords: catalysis, gaseous pollutants, liquid phase pollutants, VOCs, CO, photocatalysis, Nanostructures, nanocatalysts, adsorption, remediation
