β-MnO2 nanowires: A novel ozonation catalyst for water treatment

Role of Fe/pumice composition and structure in promoting ozonation reactions

“…In recent years, heterogeneous catalytic ozonation studies mainly focused on increasing ozone mass transfer and amount of • OH generation. Heterogeneous catalysts commonly used for this process include activated carbon [3][4][5], metal oxides [2,[6][7][8][9][10][11][12], and metals on supports [13][14][15][16][17][18][19]. However, industrial-scale application of these materials is inhibited by their complex separation, low mechanical strength, high cost, or easy oxidation.…”

Efficient catalytic ozonation by ruthenium nanoparticles supported on SiO 2 or TiO 2 : Towards the use of a non-woven fiber paper as original support

“…More recently, metal and metal oxides nanoparticles have proved to be promising catalysts for ozone decomposition, owing to their high surface specific area and a high number of surface-exposed atoms [10][11][12][13][14][15][16]. These nanoparticles are usually deposited on a support to facilitate their recovery and finally to increase their durability.…”

Comparison of catalytic ozonation of phenol by activated carbon and manganese-supported activated carbon prepared from brewing yeast

“…Heterogeneous catalytic ozonation, which is one of the most attractive alternatives, aims to enhance removal of more refractory compounds through the transformation of ozone into more reactive species and/ or through adsorption and reaction of the pollutants on the surface of the catalyst. Oxides of transition metals, such as manganese [11][12][13][14], titanium [4,5] or cobalt [15,16], are amongst the most frequently studied ozonation catalysts. It has been proven by many authors that activated carbon can act initiating the ozone decomposition [1,[17][18][19], leading to the formation of oxygenated active species that are responsible for enhancing the mineralization of organic compounds.…”
