- •
Selectivity and activity of CO2 reduction are screened by SFC-OLEMS.
- •
Product distribution is dependent from potential/current and catalyst composition.
- •
Impact of various compositions of Cu–Co catalysts is investigated.
- •
Thin film composition spread samples ensure constant surface structure.
- •
Selectivity shifts from C1 to C2 products for a Co concentration of 5–15 at.%.
