Active Site Determination of Heterogenized Molecular Electrocatalysts

Advanced Energy Materials, Volume 16, Issue 17, 6 May 2026.
Here, we develop a methodology to examine the active site availability of immobilized transition‐metal molecular complexes via cyclic voltammetry. By using varying loadings of the molecular complex FeTPP physically immobilized onto Vulcan Carbon, we show the influences of FeTPP/VC ratios on the total number of active sites.
