Ein ternär dotierter Ni‐Gd‐N‐Katalysator in porösem Kohlenstoff wurde für die elektrokatalytische CO2‐Reduktion entwickelt, wie Lang Xu et al. in ihrem Forschungsartikel berichten (e202201166). Aktive NiI‐Zentren mit hoher Produktselektivität und Ni‐Nanopartikel mit hoher Leitfähigkeit sind in einem Katalysator integriert. Gd‐Atome modulieren die Größe der Ni‐Nanopartikel sowie die lokalen Dichten...
Generally, in terms of electrocatalytic CO2 reduction, single‐atom catalysts show high selectivities yet low current densities whereas conventional nanoparticle catalysts exhibit relatively high current densities but low selectivities. This work combines the advantages of the two classes of catalysts by constructing a Ni‐Gd‐N‐doped carbon black electrocatalyst within which NiI active sites are exposed...
