“…In the first step, the ultrathin Ni MOF NSs were prepared through a liquid−liquid interfacial reaction method (Figures S1 and S2). 21 In the second step, metal ions were reduced and grew on MOFs by regulating the reduction kinetics with solvents (Figure 1). A transmission electron microscopy (TEM) image shows that the Ni MOF NSs display a 2D morphology (Figure 2a).…”

Heterojunction nanostructures usually exhibit enhanced properties in compariosn with their building blocks and are promising catalyst candidates due to their combined surface and unique interface. Here, for the first time we realized the oriented growth of ultrasmall metal nanoparticles (NPs) on metal−organic framework nanosheets (MOF NSs) by precisely regulating the reduction kinetics of metal ions with solvents. In particular, a rapid reduction of metal ions leads to the random distribution of metal NPs on the surface of MOF NSs, while a slow reduction of metal ions results in the oriented growth of NPs on the edge of MOF NSs. Impressively, the strong synergy between Pt NPs and MOF NSs significantly enhances the hydrogen evolution reaction (HER) performance, and the optimal catalyst displays HER activities superior to those of a composite with a random growth of Pt NPs and commercial Pt/C under both acidic and alkaline conditions. Moreover, the versatility of such oriented growth has been extended to other metal NPs, such as Pd, Ag, and Au. We believe this work will promote research interest in material design for many potential applications.

2D metal–organic frameworks (MOF) have demonstrated exceptional properties and advantages for applications in catalysis, membrane separation, medicine, and energy harvesting and storage systems as compared to their bulk counterpart. Despite these promises, scalable synthesis of 2D MOFs remains a frontier challenge in chemistry, which limits its potential for commercialization. This review article provides a brief overview on different 2D MOF synthetic approaches followed by recent advances toward the scalable synthesis of 2D MOFs.

“…A particular advantage that they hold is their molecularly well‐defined catalytic sites and a modular structure that could enable the extraction of discrete structure‐activity relationships. As such, only few metal‐organic structures have been applied for H 2 O 2 synthesis [16–18] . In this work, we build on these previous studies and study the effects of linker identity on Ni‐based metal‐organic nanosheets (MONs).…”

The electrochemical synthesis of hydrogen peroxide (H 2 O 2 ), a widely used oxidant, is emerging as a green alternative to the conventional anthraquinone method. In this work, Ni-based metal-organic nanosheet (NiÀ MON) catalysts constructed using a variety of linkers were studied as oxygen reduction catalysts. Using a host of analytical techniques, we reveal how modulating the terephthalic acid linker with hydroxy, amine, and fluorine groups impacts the resulting physical and electronic structure of the Ni catalytic sites. These changes further impact the catalysts' Faradaic Efficiency for H 2 O 2 , with the NiÀ AmineÀ MON reaching near 100 % FE at minimal overpotential for the 2e À H 2 O 2 pathway in alkaline electrolyte. Finally, we translate the NiÀ AmineÀ MON catalyst to a gasdiffusion reaction geometry and demonstrate a H 2 O 2 partial current density of 200 mA/cm 2 while maintaining 85 % Faradaic efficiency. In all, this study puts forth a simple route to catalyst modulation for highly effective H 2 O 2 electrosynthesis.
