英文摘要An unprecedented molecular polyanionic metal oxide cluster of eleven-FeIII substituted antimoniotungstate Na27[Fe11(H2O)14(OH)2(W3O10)2(α-SbW9O33)6]·103H2O(1) based on earth abundant elements has been successfully synthesized. A careful physical investigation of this molecule reveals that VB=−6.34 eV/CB=−4.39 eV, this unique physical properties ensures that 1 can be defined as a new type of nanoscale molecular semiconductor. This compound showed remarkable catalytic property for light driven H2 evolution activity. A H2 evolution rate of 820 μmol h−1 g−1 was achieved in the presence of 1 without adding any co-catalyst at neutral condition, which is a very high rate among all polyoxotungstate photocatalysts reported thus far. Six evidences proved that 1 is a true stable molecular catalyst during the photocatalytic hydrogen evolution.
