An Orders‐of‐Magnitude Increase in the Rate of the Solid‐Catalyzed CO Oxidation by In Situ Ball Milling

Abstract: Geschüttelt, nicht gerührt: Kohlenmonoxid wurde in einer Kugelmühle kontinuierlich oxidiert. Beim Mahlen wird die Reaktionsgeschwindigkeit deutlich erhöht, diese sinkt jedoch schnell gegen null, wenn der Mahlvorgang gestoppt wird. Die Reaktionsgeschwindigkeit der Cr2O3‐katalysierten Reaktion in der Kugelmühle ist bei Raumtemperatur drei Größenordnungen und bei 100 °C eine Größenordnung höher als bei vergleichbaren Experimenten in einem Plug‐Flow‐Reaktor.

“…The (002) reflections arises due to the interlayer scattering between parallel stacked carbon layers. The (10) and (11) reflections correspond to the intralayer scattering within the graphene layers. An additional impurity reflection at 27°is seen especially for p-CA and f-CA, which can be contributed to trapped Na 2 CO 3 from synthesis.…”

“…The mechanical energy in a planetary ball mill can not only cause the fragmentation of materials but also can induce a chemical reaction between the solid reagents. Immohr et al reported the catalytic CO oxidation under in situ ball milling conditions where the reaction rate was increased by three orders of magnitude [11]. The influence of mechanical forces on the chemical reactivity of molecules (bond breaking and formation of new bonds) was studied by Craig [12].…”
