Tunable titanium metal-organic frameworks with infinite 1D Ti-O rods for efficient visible-light-driven photocatalytic H₂ evolution.

ABSTRACT: Infinite 1D Ti-O rod-based metal-organic frameworks (MOFs) are promising photocatalysts for water splitting due to their high optical response and favourable photo-redox properties and stability, but have not been explored yet. In this study, three isoreticular porous 1D rod-based Ti-MOFs ZSTU-1, ZSTU-2 and ZSTU-3 are successfully constructed from infinite [Ti6(μ3-O)6(μ2-OH)6]n secondary building units (SBUs) and tritopic carboxylate linkers 4,4',4″-nitrilotribenzoic acid (H₃TCA), 1,3,5-tris(4-carboxyphenyl) benzene (H₃BTB) and tris(4'-carboxybiphenyl)amine (H₃BTCA), respectively. Their porosities systematically increase with the larger and longer organic linkers. The two MOFs ZSTU-1 and ZSTU-3 built from the triphenylamin
