Abstract
Improving the efficiency of photocatalysis is an extremely important fundamental task that has applications in chemistry, biology, pharmacology, and medicine. One of the ways to increase the efficiency of photocatalysis could be the use of the effect of strong coupling in the light-matter interaction, a specific physical phenomenon that has become in recent years the front line of research in the fields of fundamental and applied aspects of physics and chemistry. Among the most intriguing properties of the strong coupling effect is the ability to control the selectivity and yield of chemical reactions and multiply the efficiency of catalysis, which is achieved by the appearance, during the splitting of the original electronic level of the catalyst and/or substrate, of a higher-energy electronic level – the upper polariton. In the present work, we developed a design of a microfluidic photocatalytic reactor containing a microresonator providing a strong light-matter coupling and operating in the microfluidic mode with a productivity in the range of 0.01–0.1 mol/h. The design is based on integration of a photocatalyst (functionalized porous matrix made of boron nitride) into the cavity between the mirrors of the optical microresonator located in the microfluidic cell. It is assumed that the developed technology will significantly increase the rate of photocatalytic reactions, when the working volume of the reactor is irradiated with light of the visible range.
