Photochemical and electrochemical hydrogen evolution reactivity of lanthanide-functionalized polyoxotungstates

Abstract

The first example of hydrogen evolution reactivity (HER) of lanthanide-functionalized Keggin-based polyoxotungstates under photochemical and electrochemical conditions is reported. The HER activity under homogeneous, visible light-driven conditions and under heterogeneous, electrochemical conditions depends on the type of lanthanide functionalization, so that a new class of model HER catalysts for systematic reactivity studies is now accessible.
