"Nanomaterials from the espresso maker: polymeric carbon nitrides for photocatalytic wastewater treatment with visible light" by Malte Petersen and Jonathan Bauschulte
Abstract:
The paper presents the construction of a low-cost muffle furnace based on an espresso maker and a heating plate. This can be used to synthesise polymeric carbon nitrides based on carbon and nitrogen from urea. This group of substances is a representative of nanomaterials and can be used as a heterogeneous photocatalyst not only under UV, but also in the visible light range. This is demonstrated using the example of model pollutant degradation and enables the potential of this substance class to be tapped. The materials created have been tested several times in a school laboratory and offer various possibilities for integration into regular lessons.
