“…Therefore, the integration of noble-metal NPs with MOF photocatalysts in an appropriate manner would further improve the photocatalytic activity of MOFs. To date, various methods, including chemical vapor deposition, colloidal synthesis, and incipient wetness impregnation, have been developed to fabricate noble-metal@MOF nanocomposites (denoted as M@MOFs) [22][23][24][25][26]. However, these routes typically result in high energy consumption, large agglomerated particles with irregular morphologies, and insufficient interfacial contact between the supports and noble-metal NPs.…”

Proper design and preparation of high-performance and stable dual functional photocatalytic materials remains a significant objective of research. In this work, highly dispersed noble-metal nanoparticles (Au, Pd, Pt) were immobilized on MIL-100(Fe) (denoted M@MIL-100(Fe)) using a facile room-temperature photodeposition technique. The resulting M@MIL-100(Fe) (M = Au, Pd, and Pt) nanocomposites exhibited enhanced photoactivities toward photocatalytic degradation of methyl orange (MO) and reduction of heavy-metal Cr(VI) ions under visible-light irradiation (λ ≥ 420 nm) compared with blank-MIL-100(Fe). Combining these results with photoelectrochemical analyses revealed that noble-metal deposition can effectively improve the charge-separation efficiency of MIL-100(Fe) under visible-light irradiation. This phenomenon in turn leads to the enhancement of visible-light-driven photoactivity of M@MIL-100(Fe) toward photocatalytic redox reactions. In particular, the Pt@MIL-100(Fe) with an average Pt particle size of 2 nm exhibited remarkably enhanced photoactivities compared with those of M@MIL-100(Fe) (M = Au and Pd), which can be attributed to the integrative effect of the enhanced light absorption intensity and more efficient separation of the photogenerated charge carrier. In addition, possible photocatalytic reaction mechanisms are also proposed.

“…For instance, ultrathin Rh nanosheets exhibited selectivity of only 74% for aldehydes in the hydroformylation of 1‐octene under 5.0 MPa of H 2 /CO mixed gas at 90 °C (Figure a) . ZIF‐8 supported Rh nanoparticle catalyst showed high catalytic activity and durability to the hydroformylation of n‐alkenes, but the selectivity of branched aldehydes and linear aldehydes was not so satisfactory . In the hydroformylation of styrene, Rh‐metalated porous organic polymers showed 87.8% regioselectivity for branched aldehyde (2‐phenyl propionaldehyde) under 1 MPa of CO/H 2 at 80 °C (Figure b) …”

Rhodium (Rh) is well‐known for its catalytic application in diverse industrial reactions such as methane conversion, hydrogen generation, and olefin hydroformylation. Compared to homogeneous catalysts, heterogeneous Rh‐based nanocatalysts are facilely separated and collected after reactions, thus being more compatible for industrialization. To this end, the development of active and stable heterogeneous Rh‐based catalysts has received everlasting interest. In this review, we focus on the synthesis and catalytic application of Rh‐based nanocatalysts for heterogeneous catalysis. Recent efforts in the design and fabrication of Rh‐based nanocatalysts are highlighted. Various synthetic strategies and protocols for shape‐controlled synthesis of Rh‐based nanocrystals and supported Rh‐based nanocatalysts are overviewed. In addition, we introduce methane conversion, hydrogen generation, and olefin hydroformylation as three typical catalytic applications of the Rh‐based nanocatalysts, and provide insights into the catalytic mechanisms involved. The remaining challenges and future prospects for the Rh‐based heterogeneous nanocatalysts are also discussed. This review offers a guideline for future research on Rh‐based nanocatalysts for heterogeneous catalysis.

“…Homogeneous Rh‐based catalysts are applied in industrial processes because of their excellent catalytic activities but are difficult to separate from the reaction mixture . On the other hand, Rh nanoparticles have always suffered from poor activities . Lang and co‐workers synthesized catalysts with Rh weight loadings of 0.3 %, 0.03 %, and 0.006 % supported on ZnO nanowires (Figure ) by a facile adsorption method wherein ZnO nanowire dispersed in water was added to aqueous solution of RhCl 3 ⋅ 3 H 2 O.…”

The field of heterogeneous nanocatalysis has developed catalysts with excellent activities, superior selectivities and high stabilities. Their properties can be easily tuned by tailoring the size, shape and morphology of the nanomaterial. Thus, nanocatalysis is no longer just a field of academic curiosity, but an evolving field for industries to develop green and sustainable processes with very high turnover numbers, rates, and stabilities. The key to increase the efficiencies of these catalysts is to maximize the number of active centers on the surfaces, which can be achieved by reducing the size of metal NPs to single atom and pseudo‐single atom sizes. This field is growing exponentially, and several reports have described the syntheses, characterizations, and applications of these catalysts for a variety of reactions. This Review discusses the recent advances in the synthesis and catalytic performance of single and pseudo‐single atoms/sub‐nanometer (<1 nm) catalysts. We have reviewed experimental and theoretical studies performed for different reactions and, in the last section a brief outlook on the future prospects.
