Special Issue Information
Dear Colleagues,
Limited water resources and continuous population growth are impairing access to safe and clean water on a global scale. Pollutants in water impact hygiene, food safety and human health. All the stages of food production, including processing, transportation, and consumption, require a steady supply of clean water. Nanomaterials with properties such as high efficacy and selectivity, high surface areas, cost-efficiency, recyclability, high thermal and mechanical stability, and environmental viability are being utilized to cleanse wastewater. The use of catalytic technology is a promising approach to water treatment that uses catalysts to facilitate chemical reactions that remove or break down contaminants in water. These usually operate at lower temperatures and pressures than conventional chemical processes and can be used to increase the efficiency and selectivity of chemical reactions. Catalytic technologies imbibed with nanomaterials are utilized in adsorption, electrochemical processes, membrane filtration, magnetic separation, and biological treatment, and represent a potential solution to the increasing problems in wastewater management. The principles of catalytic technology and the different types of catalysts used in water treatment are applied in heterogeneous processes, advanced oxidation processes (AOPs), and direct oxidative transfer processes (DOTPs). This Special Issue focuses on the synthesis, characterization and application of various types of nanomaterials, such as carbon-based materials, metal nanoparticles, and metal oxides, in water treatment. It includes the application of catalytic technology, the processes underlying catalytic reactions, the development and modification of catalytic reactors, and the use of catalysts in various water treatment processes, such as the elimination of organic pollutants, heavy metals, and emerging contaminants. A case-based application of a photocatalytic reaction and photo-Fenton degradation in the mineralization of phenol is also discussed. The challenges and future applications of catalytic technology and nanomaterials for water treatment, including the creation of novel catalysts and nanomaterials, process optimization, and the fusion of various treatment modalities, are also within the scope of this Special Issue.
Although many nanomaterial-based catalytic technologies are already applied in water treatment, the field is rapidly advancing into new areas of discovery.
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.
