Constructing the rigorous evaluation method for the formation rate of hydroxyl radical by titanium dioxide catalyst under the ultrasonic irradiation

建立了超声辐照下二氧化钛催化剂生成羟基自由基速率的严格评价方法。首先，利用自旋标记物种与羟基自由基反应的动力学模型，估算了无二氧化钛条件下羟基自由基的生成速率。然后，利用考虑自旋标记物种在二氧化钛表面的吸附的动力学模型，估算了二氧化钛存在下的羟基自由基生成速率。

The rigorous evaluation method for the formation rate of hydroxyl radical by titanium dioxide catalyst under the ultrasonic irradiation has been constructed. At first, the formation rate of hydroxyl radical in the absence of titanium dioxide was evaluated by using a kinetic model for the reaction between spin label species and hydroxyl radical. Then, the formation rate of hydroxyl radical in the presence of titanium dioxide was evaluated by using a kinetic model considering the adsorption of spin label species onto titanium dioxide.
