Many industries, such as chemical, pharmaceutical, petrochemical, agrochemical, and textile, yield high amounts of organic pollutants in water. For environmental protection, the treatment of wastewaters should aim to totally remove organic pollutants efficiently and sustainably. After conventional methods are used, suitable catalytic processes are needed to totally eliminate the organic pollutants, e.g. phenol, substituted phenols, chlorinated compounds, pesticides, textile azo-dyes, synthetic hormones, emerging contaminants, and pharmaceutical products in diluted media. These catalytic processes should be improved to ensure minimal consumption of energy and no negative impact on environment.

The current challenge in this area is to synthesize new solid structures with high catalytic activity for the total oxidation of these organic pollutants in diluted aqueous solutions, ideally at room temperature, atmospheric pressure and without radiation assistance. Some inorganic structures such as transition metal oxides, mixed oxides, hierarchical materials, modified clays, modified zeolites, metal-organic frameworks (MOFs), composites materials and other crystalline or amorphous materials have been investigated for the aforementioned purpose.

In this Research Topic we present the latest outstanding research on the synthesis of innovative inorganic structures with high catalytic activity in the oxidation of industrial organic pollutants in water. This Research Topic welcomes original research papers, and areas to be covered include:

1. Synthesis of new solid inorganic structures with efficient catalytic activity in non-irradiated advanced oxidation processes.
2. Application of natural or modified inorganic minerals in the total oxidation of organic pollutants in water.
3. Heterogenous catalytic wet peroxide oxidation of industrial pollutants in real or modeled wastewater.
4. Microporous and mesoporous materials for the catalytic wet oxidation of industrial wastewater containing organic pollutants.
5. New studies on chemical mechanisms or reaction pathways of the emerging pollutant degradations in water, by using inorganic solid structures as catalysts in non-irradiated advanced oxidation processes.
