Phase Engineering of Fe-Polyoxometalate Sub-1 nm Assemblies for High-Efficiency Photoelectrocatalytic Nitrogen Reduction
, representing a 4.47-fold enhancement over the discrete clusters. Experimental and theoretical evidence demonstrate that electron delocalization among Fe-POM assemblies results in narrower band gaps and enhanced light harvesting, which also lowers the energy barrier for the rate-determining step (*NNH formation). Different from the microenvironment design of active sites, the superstructural engineering may offer a versatile paradigm for the electronic structure modulation of catalysts.
