A d10 metal–organic framework ([Hg­(Bpbp)­(SCN)2]n (CQNU-1, Bpbp = 4,4′-bis­(4-pyridyl)­biphenyl) has been synthesized and evaluated as a photocatalyst for water splitting. UV–vis spectra and Mott–Schottky analysis indicate that CQNU-1 is a potential photocatalyst with dual functions of hydrogen and oxygen evolution. The results of photocatalytic reactions over CQNU-1 show that, in the presence of a sacrificial agent, the average H2 and O2 evolution rates obtained by the pristine CQNU-1 are ∼7.0 and ∼3.4 μmol h–1 during a 9 h test with three cycles, respectively.
