The present article describes the hydrogen production from an aqueous medium over amino-functionalized Ti(IV) metal–organic framework (Ti-MOF-NH2) under visible-light irradiation. Ti-MOF-NH2, which employs 2-amino-benzenedicarboxylic acid as organic linker, has been synthesized by a facile solvothermal method. Pt nanoparticles cocatalysts are then deposited onto Ti-MOF-NH2 via photodeposition process (Pt/Ti-MOF-NH2). XRD and N2 adsorption measurements reveal successful formation of MOF...
Efficient hydrogen production and photocatalytic reduction of nitrobenzene were achieved by using a Pt-deposited amino-functionalised Ti(IV) metal–organic framework (Pt/Ti-MOF-NH2) under visible-light irradiation. XRD N2 adsorption measurements revealed that crystalline microporous structures formed maintained even after the Pt deposition. The activity for visible-light-promoted was improved through optimization deposition amount as cocatalyst. optimised determined to be 1.5 wt%. results in...
A Ru complex-incorporated Ti-based MOF (Ti-MOF-Ru(tpy)2) has been synthesised by using a bis(4′-(4-carboxyphenyl)-terpyridine)Ru(II) complex (Ru(tpy)2) as an organic linker.

The present perspective describes recent advances in visible-light-responsive photocatalysts intended to develop novel and efficient solar energy conversion technologies, including water splitting photofuel cells. Water is recognized as one of the most promising techniques convert a clean abundant resource into chemical form hydrogen. In years, increasing concern directed not only development new photocatalytic materials but also importance technologies produce hydrogen oxygen separately....
