Photocatalytic water splitting for hydrogen and oxygen evolution using cobalt- substituted polyoxometalates
The synthesis and photocatalytic properties of cobalt-incorporated polyoxometalate H18[α1-P2W17Co(H2O)O61]-[Co4(H2O)2(PW9O34)2] (1) were reported, and split into α1-H8-[P2W17Co(H2O)O61] (2) and H10[Co4(H2O)2(PW9O34)2] (3) by adjusting the types of acids and solvents in the reaction. The photocatalytic production of O2 and H2 from water by compounds 1, 2 and 3 was evaluated. Notably, compounds 1 and 2 demonstrate superior performance in the photocatalytic production of both hydrogen and oxygen, whereas compound 3 solely exhibits activity in the photocatalytic generation of oxygen. The significantly enhanced performance against the control [P2W18O62]6− can be attributed to the modulation of the electronic structures of these novel POMs facilitated by the incorporation of cobalt.
