New reactor for 3D in situ imaging of catalysts
Research obtains 3D images of catalysts under reaction by Bragg coherent X-ray diffraction
Catalysts are materials that promote and accelerate chemical reactions without being consumed during the process. For example, catalysts are used, for example, to reduce the emission of toxic gases, such as the carbon monoxide ($\rm CO$) produced by car engines.
The catalytic converters present in the exhaust of vehicles allows the $\rm CO$ oxidation reaction to occur, that is, in the presence of a catalyst, $\rm CO$ reacts with the oxygen gas ($\rm O_2$) leading to the formation of carbon dioxide ($\rm CO_2$).
Hence, to achieve cheaper and more efficient processes to control vehicle pollution, a better understanding of catalytic materials is needed. Consequently, to carry out such challenging researches, the development of new scientific tools is constantly necessary.
