Novel materials for catalytic ozonation of wastewater for disinfection and removal of micropollutants

Complementary Bifunctional Unique Properties of (α,β)‐PbO Nanoparticles for Efficient Catalysis and Adsorption for Water Remediation

“…formed during ozonolysis. Furthermore, the efficiency of ozonolysis also depends on the pH of the solution . The low utilization of O 3 due to its poor stability and solubility in water makes the process economically unfavourable …”

“…Overcoming these limitations, the heterogeneous catalytic ozonation is emerging as better alternative for degradation of refractory organic moieties . The presence of the catalyst increases mass transfer of O 3 from gas to solution phase and decomposition of O 3 at the surface of catalysts generates significant amount of stronger oxidant hydroxyl radical ( .…”

“…OH), which can accelerate the kinetics of mineralization of refractory organic pollutants in wider range of pH . Recently, micro‐ and nano‐dimensional transition and non‐transition metal oxides have been widely studied as catalysts for ozonation reaction for the degradation of various organic pollutants (as shown in Table S1) ; but many of those catalysts was evident to be effective only at low and near to neutral pH. On the contrary, pH of the dye effluent of most of the textile industries roughly varies in the range of neutral to alkaline …”
