“…Yuan et al [ 65 ] used pumice, a porous natural glass formed from volcanic activity with a relatively high concentration of silica, aluminum and iron. This material has been tested as a photocatalyst [ 168 ], a catalyst in the Fenton-like reaction [ 169 ] and as an adsorbent [ 170 ] in different water treatment processes. In this particular study, pumice was tested as a catalyst in the ozonation of trace concentrations of p -chloronitrobenzene ( p- CNB).…”

Ozone has been successfully employed in water treatment due to its ability to oxidize a wide variety of refractory compounds. In order to increase the process efficiency and optimize its economy, the implementation of heterogeneous catalysts has been encouraged. In this context, the use of cheap and widely available natural materials is a promising option that would promote the utilization of ozone in a cost-effective water treatment process. This review describes the use of natural clays, zeolites and oxides as supports or active catalysts in the ozonation process, with emphasis on the structural characteristics and modifications performed in the raw natural materials; the catalytic oxidation mechanism; effect of the operating parameters and degradation efficiency outcomes. According to the information compiled, more research in realistic scenarios is needed (i.e., real wastewater matrix or continuous operation in pilot scale) in order to transfer this technology to the treatment of real wastewater streams.

“…These methods are mainly based on the production of reactive oxygen species such as non-selective and highly reactive hydroxyl radicals and sulfate radicals in sufficient quantity to oxidize and mineralize refractory organic contaminants into carbon dioxide, water, and inorganic acids at ambient temperatures. [15][16][17] Sulfate radicals-based AOPs have gained increasing attention of many researchers as a simple and effective way for degradation and mineralization of recalcitrant organic pollutants in water. 18 In such methods, peroxymonosulfate (PMS) or peroxydisulfate (PDS) are commonly activated to produce sulphate radicals.…”
