How do Convex Lenses Enhance Photocatalytic Reactions?
In photocatalysis, light is absorbed by a catalyst to produce excited states that facilitate chemical transformations. Convex lenses can concentrate light on the catalyst surface, increasing the number of photons absorbed and hence, the number of excited states generated. This leads to a higher rate of reaction. For example, in water splitting and pollutant degradation processes, the use of convex lenses can significantly enhance the efficiency of the photocatalysts.
