Various photocatalysts have been developed for photocatalytic water splitting—one of the most importantprocesses that produces dihydrogen as clean energy for fuel cells. The successful achievements for this applicationare based mainly on transition metal oxides and some metal sulfides/nitrides. Recently, metal–organicframeworks (MOFs), a class of hybrid functional materials comprising organic backbone tethered infinitively inlimitless way by metal-oxide clusters, both of which can be customized accurately at the molecular level fortargeted applications, have been able to photocatalytically degrade water. Apart from representing an array ofintrinsic structural and physicochemical characteristics, MOFs are well susceptible for various post-syntheticmodifications to address specific challenges. Despite years of research in this field and a good number of seminalstudies, further efforts should be geared toward the improvement of light absorption and stability of MOFs,which are the principal challenges that should be overcome. This review includes the most recent research thathas been committed to MOFs materials for photocatalytic water-splitting applications. It also encompasses avariety of synthetic techniques and post-modifications that have been employed to increase the performance ofMOFs. In addition, a brief discussion of the techno-feasibility analysis of water splitting has been offered,extending the conversation to include current challenges and future direction recommendations. The recentadvancements of using MOF photocatalysts for water splitting are further described in a way that benchmarkachievements and limitations are considered so that the readers can imagine the big picture in this field and payconsiderable attention to future solutions.
