“…Also notice that the CB of CdS is more negative than the CB of UiO-66, and the electrons transfer from the CB of UiO-66 to CB of CdS is thermodynamically prohibited. Thus, it has been environed that S-scheme is more in electron-hole separation in which a high redox ability of photoinduced charge carriers can be maintained, when compared with traditional type-II heterojunction [56][57][58][59]. Following such principle, when UiO-66 and CdS are in close contact, the electrons from CdS of a higher Fermi level will transfer to the UiO-66 of a lower Fermi level across their interface until their Fermi levels are equal.…”

Unveiling the pore-size performance of metal organic frameworks (MOFs) is imperative for controllable design of sophisticated catalysts. Herein, UiO-66 with distinct macropores and mesopores were intentionally created and served as substrates to create advanced CdS/UiO-66 catalysts. The pore size impacted the spatial distribution of CdS nanoparticles (NPs): CdS tended to deposit on the external surface of mesoporous UiO-66, but spontaneously penetrated into the large cavity of macroporous UiO-66 nanocage. Normalized to unit amount of CdS, the photocatalytic reaction constant of macroporous CdS/UiO-66 over 4-nitroaniline reduction was ~3 folds of that of mesoporous counterpart, and outperformed many other reported state-of-art CdS-based catalysts. A confinement effect of CdS NPs within UiO-66 cage could respond for its high activity, which could shorten the electron-transport distance of NPs-MOFs-reactant, and protect the active CdS NPs from photocorrosion. The finding here provides a straightforward paradigm and mechanism to rationally fabricate advance NPs/ MOFs for diverse applications.

currents, geothermal, biomass, and solar, have been developed as alternatives. Among them, solar energy is the most abundant, inexpensive, nonpolluting, and sustainable. [5][6][7][8] Some semiconductors, so called photocatalysts, which possess the capacity to harvest solar energy to drive catalytic reactions for valuable chemical production, have been designed and fabricated to achieve efficient solar energy utilization. [9][10][11][12][13][14][15][16][17][18][19] Typically, TiO 2 is recognized as one of the most promising candidates due to its chemical stability, nontoxicity, and high resistance to photocorrosion. [20][21][22][23][24][25] In general, TiO 2 possesses three major phases, including anatase, rutile and brookite, and many other minor phases, such as monoclinic TiO 2 (B). All of them have wide bandgaps of 3.0-3.2 eV. Hence, TiO 2 can only absorb ultraviolet light (UV), while the visible light accounting for ≈43% of solar energy cannot be utilized. Furthermore, the rapid recombination of photogenerated electrons and holes severely limits its quantum efficiency. Thus, overall photocatalytic activity of TiO 2 is very limited, especially under visiblelight irradiation. [26][27][28] A complete photocatalytic reaction using TiO 2 -based photocatalysts involves three major steps: i) light absorption and The photocatalytic properties of TiO 2 have aroused a broad range of research interest since 1972 due to its abundance, chemical stability, and easily available nature. To increase its overall activity, in the past few decades, much effort has been devoted to the fabrication of advanced TiO 2 -based photocatalysts with visible-light response and these photocatalysts have shown great potential in the field of solar energy utilization. Here, recent progress in the investigation of visible-light responsive TiO 2 -based materials are reviewed. Notably, the fabrication strategies and corresponding chemical/ physical properties of visible-light responsive TiO 2 -based materials are described in detail, with a focus on bandgap engineering and junction engineering from the perspective of light absorption, charge transfer and separation, and surface reactions. Their applications in solar-fuel production, organic synthesis, bacterial disinfection, pollutant degradation and nitrogen fixation are also discussed. Moreover, the new trends and ongoing challenges in this field are proposed and highlighted.
