When conducting a photooxidation reaction, the key question is what is the best amount of photocatalyst to be used in the reaction? This work demonstrates a fast and simple method to calculate a reliable concentration of the photocatalyst that will ensure an efficient reaction. The determination is based on shifting the calculation away from the concentration of the compound to be oxidized to utilizing the limitations on the total light dose that can be delivered to the catalyst. These limitations are defined by the photoflow setup, specifically the channel height and the emission peak of the light source. This method was tested and shown to work well for three catalysts with different absorption properties through using LEDs with emission maxima close to the absorption maximum of each catalyst.

确定在连续流反应器中进行的光氧化反应的正确光催化剂浓度的方法。

进行光氧化反应时，关键问题是反应中使用的最佳光催化剂量是多少？这项工作演示了一种快速简单的方法来计算可靠的光催化剂浓度，这将确保有效的反应。该确定是基于将计算的方向从要氧化的化合物的浓度转移到利用可以传递给催化剂的总光剂量的限制。这些限制由光流设置定义，特别是通道高度和光源的发射峰。通过使用发射最大值接近每种催化剂的吸收最大值的LED，测试了该方法并证明了该方法对于三种具有不同吸收特性的催化剂的效果很好。
