Two Nickel-added Poly(polyoxometalate)s Built by Keggin-Type {Ni6PW9} and Anderson-Type NiW6O24 via WO4/Sb2O bridges and Ni–O–W linkages with Efficient Hydrogen Evolution Activity

Two Ni-added poly(POM)s built of {Ni 6 PW 9 } and NiW 6 O 24 units via WO 4 /Sb 2 O and Ni–O–W bonds have been made, which work as heterogeneous catalysts for light-driven hydrogen evolution, showing superior to most of the reported POM-based catalysts.
