“…Recently, there are a few publications on the ozonation of DMP to study its degradation and TOC removal with the presence of catalyst or UV radiation [17][18][19][20][21][22][23], such as the catalytic ozonation of DMP in the presence of heterogeneous Ru/Al 2 O 3 , Ru or Ce/AC (activated carbon) catalyst [17][18][19]. The results indicated that the mineralization of DMP during ozonation could be promoted by the use of Ru/Al 2 O 3 , Ru or Ce/AC catalyst because of improvement of mass transfer, but the preparation of Ru/Al 2 O 3 , Ru/AC catalyst is relatively expensive.…”

“…On the other hand, the total organic carbon (TOC) removals were stable around 75% for a duration of 42 h and no trace of Ru was observed from the reactor in the continuous experiments of Ru/AC catalyzed ozonation of DMP. Consequently, Ru/ AC catalyzed ozonation was found to be more efficient than ozonation alone for TOC removals in the natural water treatment [22].…”

Research and development in chemical engineering is currently focused on design of highly active and selective catalytic systems for process intensification. In recent years, there has been growing interest in the use of catalysts based on nanosized metal particles to improve catalytic processes. Among the many metal catalysts, platinum group metals (PGMs) have received greater attention because of their physical and catalytic properties. They have found applications in a wide range of chemical conversion and environmental decontamination reactions due to their chemical stability and enhanced catalytic reactivity in the nano range. This chapter reviews some of the major innovative applications of PGM nanocatalysts for catalytic environmental decontamination.

“…At present, the development and application of noble metal catalysts are interesting for research [20][21][22]. The noble metals are usually loaded onto supports including metal oxide and activated carbon for preventing their loss [23,24]. However, these catalysts are generally more expensive than the metal oxide typically used for industrial applications on water treatment.…”

Dissolved organic matter (DOM) is a typical kind of pollutant with a complex composition, and different advanced treatments demonstrate different abilities toward its fractional removal. Hence, it is necessary to analyze the fraction of DOM that remains when using advanced treatments. In this paper, ozonation was used to deal with the biological effluents and comparisons of the catalytic ozonation with different particle sizes of γ-Al2O3 were made. The results of these comparisons indicated that the catalysts were active in improving the removal of DOM and γ-Al2O3 with different particle sizes can selectively remove DOM. The result of fluorescence showed that a decrease in the catalyst particle size contributes to a significant decrease in the fluorescence intensity, except for tryptophan-like substances. Meanwhile, DOM fractions with large molecular weights could be decomposed into small molecules by ozonation, resulting in increased hydrophilicity. However, the use of a catalyst in ozonation increased the removal of hydrophilic components. Additionally, a smaller catalyst particle size increased the removal of hydrophilic components. The results of catalyst analysis implied that the surface hydroxyl groups of catalyst γ-Al2O3 and the diffusion of DOM in the catalyst γ-Al2O3 played important roles in the ozonation catalytic process for the removal of DOM.
