Constructing Two Cu-Modified Organophosphomolybdates from a Nanocluster to a One-Dimensional Chain for Boosted Visible-Light-Driven Hydrogen Production.

Photocatalytic decomposition of water to produce hydrogen H is an ideal way to solve energy and environmental problems, and the development of highly efficient polyoxometalate catalysts for photocatalytic hydrogen production has attracted wide attention. Herein, two Cu-modified Strandberg-type organophosphomolybdates were successfully synthesized, [Cu(CHN)(HO)][(CHPO)MoO]·4HO () and [Cu(phen)(HO)][Cu(phen)(HO)][(CHPO)MoO]·2HO () ([(CHP)MoO]Cu) (CHN = 2-(1H-pyrazol-3-yl)pyridine, phen = 1,10-phenanthroline). Two Strandberg-type organophosphomolybdates can be used for visible-light-driven hydrogen production.
