“…Moreover, computational studies have indicated that atoms of metals such as Au, Cu, and Mo on defective h‐BN could be active electrocatalysts for CO oxidation or nitrogen fixation . From experimental studies, it is proposed that both precious and non‐precious metal nanoparticles on highly defective h‐BN nanosheets are excellent systems for the electrocatalysis of CO oxidation, for the hydrogenation of nitroaromatics, for the Suzuki–Miyaura reaction, and for the Fischer–Tropsch synthesis …”

Metal‐doped and metal‐supported two‐dimensional materials are attracting a lot of interest as potentially active electrocatalysts for reduction and oxidation processes. Previously, when a non‐regular 2 D h‐BN layer was grown on a Cu(111) surface, metal adatoms were found to spontaneously emerge from the bulk to fill the atomic holes in the structure and become available for surface catalysis. Herein, computational electrochemistry is used to investigate and compare the performance of Cu‐doped and Cu‐supported pristine and defective h‐BN systems for the electrocatalytic water oxidation reaction. For the various model systems, the intermediate species of this multistep oxidation process are identified and the free‐energy variations for each step of reaction are computed, even for those steps that do not involve an electron or a proton transfer. Both associative and O2 direct evolution mechanisms are considered. On this thermodynamic basis, the potential‐determining step, the thermodynamic‐determining step, and consequently the theoretical overpotential are determined for comparison with experiments. Small Cu clusters (tetramers) trapped in the h‐BN defective lattice on a Cu(111) support are found to be very active for the water oxidation reaction since such systems are characterized by a low overpotential and by a small energy cost for O2 release from the catalyst, which is often observed to be a major limit for other potential electrocatalysts.

“…The resultant Pd/BNNS catalyst exhibited high catalytic activity and recyclability towards hydrogenation of nitro aromatics. Further, Lu and co‐workers reported BNNS‐anchored bimetallic PdFe NPs (PdFe/BNNS) by a chemical reduction method using NaBH 4 as the reducing agent and explored its catalytic activity towards the Suzuki–Miyaura coupling reaction . The TEM and energy‐dispersive X‐ray spectroscopy (EDS) analysis revealed that Pd–Fe core–shell NPs with relatively thick Fe shells were anchored on or close to the defective edges of the BNNS.…”

Since the successful isolation of graphene, two-dimensional (2D) materials have attracted immense interest in contemporary chemical research owing to their unique structural and chemical properties with potentials cientific applications. Layered2 Dm aterials show differentc haracteristics from bulk 3D materials owing to significanta lterations in their electronic and structural behavior.F rom the last decade, 2D materials including grapheneh ave been extensively investigated as supports for metal nanoparticles (NPs) exhibiting excellent catalytic activity towards various chemical and electrochemical reactions.T his review focuseso nt he recent advances of graphene and other 2D layered materials as catalyst supports, their interactions with metal precursors, and catalytic applications. The catalytic behavior of metal NPs supported on 2D materials has been discussed regarding various electrochemical oxidation and reduction reactions in fuel cells as wella sn umerous organic reactions and catalytic hydrogen generation from the dehydrogenationo f hydrogen storagem aterials. We appraise that the catalytic behavior of the nanomaterials can be improved by simply modifying the interactions between precursors and supports by changing the chemical and physical properties of the support materials. Finally,w es ummarize the review with an outlooko nf uture opportunities and challenges of 2D materials to provide access to av ariety of low-costa nd high-performance catalysts in terms of both academic and industrial applications.

“…In comparison, the heterogeneous catalysts of Pd clusters or nanoparticles (NPs) on solid supports may overcome these limitations and thus have been paid much attention. [7][8][9][10] Nonetheless, these heterogeneous catalysts usually suffer from less exposed active sites and limited accessibility for reactants, compared with their Single-atom (SA) catalysis bridging homogeneous and heterogeneous catalysis offers new opportunities for organic synthesis, but developing SA catalysts with high activity and stability is still a great challenge. Herein, a heterogeneous catalyst of Pd SAs anchored in 3D ordered macroporous ceria (Pd-SAs/3DOM-CeO 2 ) is developed through a facile template-assisted pyrolysis method.…”

Single‐atom (SA) catalysis bridging homogeneous and heterogeneous catalysis offers new opportunities for organic synthesis, but developing SA catalysts with high activity and stability is still a great challenge. Herein, a heterogeneous catalyst of Pd SAs anchored in 3D ordered macroporous ceria (Pd‐SAs/3DOM‐CeO2) is developed through a facile template‐assisted pyrolysis method. The high specific surface area of 3DOM CeO2 facilitates the heavily anchoring of Pd SAs, while the introduction of Pd atoms induces the generation of surface oxygen vacancies and prevents the grain growth of CeO2 support. The Pd‐SAs/3DOM‐CeO2 catalyst exhibits excellent activity toward Suzuki coupling reactions for a broad scope of substrates under ambient conditions, and the Pd SAs can be stabilized in CeO2 in long‐term catalytic cycles without leaching or aggregating. Theoretical calculations indicate that the CeO2 supported Pd SAs can remarkably reduce the energy barriers of both transmetalation and reductive elimination steps for Suzuki coupling reactions. The strong metal‐support interaction contributes to modulating the electronic state and maintaining the stability of Pd SA sites. This work demonstrates an effective strategy to design and synthesize stable single‐atom catalysts as well as sheds new light on the origin for enhanced catalysis based on the strong metal‐support interactions.
