Researchers at Fritz-Haber Institute of the Max Planck Society have devised a most advanced to date Hummingbird bulk liquid cell system in SEM to demonstrate an accurate and consistent way to deposit copper oxide catalysts in various shapes and sizes. The study made use of the reliable reference electrode system incorporated in the bulk liquid system to quantitatively track the electrodeposited copper cubes with different facets and sizes. For example, the growth starts from nuclei during the first cycle and deposition and dissolution of selective crystals occurs in the third and subsequent cycles. The work published in The Journal of Physical Chemistry C can provide insights into developing catalysts to convert carbon dioxide into useful chemicals and fuels.
