Organic Pollutants Degradation Using Pulseless Corona Discharge: Application in Ultrapure Water Production

Interaction Mechanisms and Application of Ozone Micro/Nanobubbles and Nanoparticles: A Review and Perspective

“…Ozone micro/nanobubble technology can solve the problems of low ozone utilization, selectivity of ozone oxidation and slow gas-liquid mass transfer rate in traditional ozone catalytic oxidation technology for water treatment [82,103]. The presence of microbubbles can accelerate the decomposition of hydroxyl radicals of ozone [17,18] and greatly improve the mineralization efficiency of refractory organics [19][20][21]. Moreover, micro/nanobubbles can also keep the catalyst in a dynamic discrete state, which effectively increases the contact frequency between the catalyst and refractory organics [12,22,23], contributes to the oxidative degradation of refractory organics and gives ozone catalytic oxidation technology broader application prospects in the field of water treatment.…”

“…Micro/nanobubble technology overcomes the limitations of traditional ozone catalytic oxidation technology and effectively improves the utilization rate and mass transfer rate of ozone [17,18]. Micro/nanobubbles can not only accelerate the decomposition of ozone's hydroxyl radicals, but also release many hydroxyl radicals, which greatly improves the mineralization efficiency of refractory organic compounds [19][20][21]. At the same time, the presence of micro/nanobubbles can also keep the catalyst in a dynamic discrete state, which effectively increases the contact frequency between the catalyst and refractory organic matter and contributes to improving the mineralization efficiency of refractory organic matter [12,22,23].…”
