“…After consulting the literatures (Fig. 2(d) and Table S1), under unit amount of CdS, Mac-Cd/UiO also outperformed many other state-of-art CdS-based nanomaterials reported in recent years [33,[48][49][50][51][52][53][54]. Such a result highlights that macroporous MOFs-based nanocage is superior in constructing of advanced catalysts.…”

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.

“…According to the report, CdS-modified MIL-68(Fe) nanocomposites were prepared by a dexterous photodeposition method at room temperature. [86] Under N 2 atmosphere, they were turn out to be the photocatalysts for the selective reduction of 4-nitroaniline to p-phenylenediamine with HCOONH 4 as the sacrificial reducing agent in water (Scheme 26d).…”

Metal Sulfide Photocatalysis: Visible‐Light‐Induced Organic Transformations

metal sulfides belong to an important subgroup of semiconductor photocatalysts that could promote a variety of valuable redox reactions under mild conditions. One notable merit of metal sulfides is their relatively smaller bandgaps than metal oxides, which in turn make sure that many of them can directly utilize visible light. Historically, the deployment of metal sulfides for visible-light-induced organic transformations took place shortly after the genesis of the research field of heterogeneous photocatalysis. In this review, we primarily focus on recent state-of-the-art advancements of metal sulfide photocatalysis aimed at visible-light-induced selective organic transformations. Interests in this specific branch of photocatalysis have been rekindled due to the new methods for materials synthesis; the pursuit of new mechanisms; or the integration of metal sulfides with metal oxides, metal nanoparticles or other emerging materials. Thus we categorize them into four sections according to the different strategies in developing novel or more efficient organic processes. Binary and ternary metal sulfides, usually associated with new materials synthesis and mechanistic insights, can be used directly for visible-lightinduced organic transformations. This is the basis of other further developments and will be introduced firstly. Next, the cooperation between metal sulfides and metal oxides or metal nanoparticles can be conducive to many photocatalytic systems. These developments will be discussed in the next two ensuing sections. Furthermore, the integration of metal sulfides with recent developed emerging materials such as metalorganic frameworks (MOFs), graphene and graphitic carbon nitride (g-C 3 N 4 ) will be discussed in another section to highlight the importance of merging metal sulfides with these materials. We attempt to keep an impartial panorama of these four distinctive sections even though the phases of development are quite different among sections, leaving plenty of room for the future expansion of this burgeoning area.

“…The 4-phenylenediamine (4-PDA) is a widely used industrial chemical raw material. It can be used in the preparation of azo dyes, as well as in the preparation of developers, rubber antioxidants, and copper-iron indicators [4][5][6][7][8] . The industrial preparation of 4-PDA is mainly prepared by using 4-nitroaniline (4-NA) as raw material and adopting industrial hydrogenation 9,10 .…”
