Gunji and co-workers measured the work function of various Pd-based alloys for electrocatalytic CO₂ reduction materials with AC-3 and reported their study on Chemistry of Materials^[1].
The CO₂ reduction reaction is dragging many attractions nowadays when many countries are claiming the carbon neutral plan.
Gunji and co-workers succeeded in the synthesis of Pd-based electrocatalysts and reduced the CO₂ into CO and HCOOH with prepared catalysts. And by measuring the work function of those catalysts with AC-3, an obvious relationship between the products selectivity and the work function was found.
With this result, AC-3 is proved to be so useful that contribute to those novel researches for climate problems.
