With an increasing world population, the demand for basic raw materials and concluding products is increasing exponentially. With increasing global industrialization, there is an increasing release of untreated waste to our ecosystem. According to an estimation, over 700 emerging pollutants such as waste contaminants of petrochemicals, personal care, textiles, and pesticides are being confirmed in the aquatic ecosystem of the European region. In addition, for energy demand, the world is mostly dependent on fossil fuel which releases heavy amounts of greenhouse gases such as carbon dioxide. Contamination of water has resulted in the development of various infectious diseases and pathogens. Over the last few decades, drug resistance has been developed in many pathogens owing to the excessive use of antibiotics.

To overcome the deadly effects of untreated waste, it is necessary to develop such chemical processes which are efficient and environmentally friendly and to find solutions to treat waste coming from industries. Catalytic reactions account for around 85-90% of all chemical reactions. From the last few decades, environmental catalysis has been widely applied in various commercial and industrial sectors for the sake of protection of the environment and for the improvement of the quality of our life. Homogeneous and heterogeneous catalysts are efficiently used to reduce water pollution, to oxidize organic particulates, to reduce the emission of nitrogen oxides from power plants, to remove waste and pesticides, and to control the emission of volatile organic compounds, etc.

This Special Issue aims to cover the recent progress and novel trends in the field of catalysis processes for environmental applications. We welcome original research and review articles discussing the state of the art.

Potential topics include but are not limited to the following:

• Green synthesis of nanomaterials for water treatment
• Catalytic activation of oxidants (e.g., advanced oxidation processes and sulfate radical-based processes) in water treatment
• Photocatalytic removal of pollutants in water treatment
• Electrocatalysis for water treatment
• Removal of pesticides, dyes, and organics
• Catalytic conversion of carbon dioxide into value-added chemicals and fuels
• Catalytic removal of pollutants in water treatment
