“…It is well known that dye-sensitized photocatalysts could expand absorption band edge and intensity, typically a metal complex photosensitizer. In 2014, He and coworkers described the application of UiO-66 and Pt@UiO-66, using rhodamine B as photosensitizer, in these systems, and the catalytic activities were 33 and 116 μmol g −1 h −1 , respectively [46]. This work successfully extended the range of UiO-66 absorption to visible light, but the activity of hydrogen production of the system was still low.…”

The application of metal-organic framework (MOF) in the field of photocatalysis is limited, because of its unstable chemical properties and failure to respond in visible light. Herein, the Pd/MOF catalysts were prepared by impregnation reduction. It is important that we have reasonably constructed the dye-sensitized system of Pd/MOF and successfully extended the application of MOF to the visible range. It exhibited maximal photocatalytic activity (9.43 mmol/g) under visible-light irradiation (λ ≥ 420 nm) with eosin Y as a photo-sensitizer, which was enhanced twice the order of magnitude compared with the pure MOF (0.03 mmol/g). The activation process with an exchangeable guest solvent produced the Zr-MOF with the high surface area and the high stability, which provide a great electronic transmission capacity. The Pd nanoparticles provide an electronic outlet, and the dye broadens the spectral absorption range. The synergistic effect of the various components contributes to the high hydrogen production activity. This work provides a reference for the application of MOF in the field of photocatalysis.

“…date, various organic dyes, such as Eosin Blue, [36] rhodamine B, [36,37] Eosin Y, [38,39] and coumarine, [40,41] adsorbed on platinum-loaded semiconductors were found to be active for H 2 evolution from an aqueous solution containing electron donor. Among all organic sensitizers, Eosin Y showed maximum efficiency in hydrogen evolution (above 100 mmol h À1 ) after sensitizing Pt/TiO 2 nanoparticles, even higher than ruthenium-based dyes.…”

Two organic donor-acceptor-π-acceptor (D-A-π-A) sensitizers (AQ and AP), containing quinoxaline/pyrido[3,4-b]pyrazine as the auxiliary acceptor, have been. Through fine-tuning of the auxiliary acceptor, a higher designed and synthesized photoelectric conversion efficiency of 6.02% for the AQ-based dye-sensitized solar cells under standard global AM1.5 solar conditions was achieved. Also, it was found that AQ-Pt/TiO2 photocatalysts displayed a better rate of H2 evolution under visible-light irradiation (420 nm<λ<780 nm) because of the stability of the oxidized states and the lower rates of electron recombination. Importantly, sensitizers AQ and AP-Pt/TiO2 showed strong photocatalytic activity during continuous light soaking for 10 h with methanol as the sacrificial electron donor. Additionally, the processes of their intermolecular electron transfer were further investigated theoretically by using time-dependent DFT. The calculated results indicate that the auxiliary acceptor plays the role of an electron trap and results in broad spectral responses.

“…In a similar fashion He et al [40] employed a UiO-66(Zr) framework as a platform to immobilize Pt nanoparticles as hydrogen evolution catalyst. In conjunction with Rhodamine B as photosensitizer, photocatalytic hydrogen formation under visible light irradiation in Catalysts used are Pt-nanoparticles [40][41][42] or the molecular diiron complex [FeFe](dcbdt)(CO) 6 [43] aqueous solution pH 7 containing 10 % TEOA as sacrificial donor could be demonstrated.…”

Metal-Organic Frameworks (MOFs) have attracted increasing attention for the creation of solid-state platforms for catalysis applications. In this review article, we present strategies to employ MOF-based materials in photochemical hydrogen production. The scope ranges from the incorporation of single functions (catalyst or photosensitizer) to multifunctional MOFs that combine both light-harvesting and catalysis in one scaffold.
