The first polyoxometalate (POM)-encapsulated twenty-four-nucleus organophosphorus-copper nanocage cluster organic framework has been constructed. Here, the phosphomolybdate POMs were incorporated into an octahedral nanocage cluster organic framework, and the resulting material exhibited highly efficient bifunctional electrochemical performance. The crystalline material showed a high specific capacitance of 366.3 F g-1 at a current density of 3 A g-1.

Ammonia synthesis via nitrate electroreduction is more attractive and sustainable than the energy-extensive Haber-Bosch process and intrinsically sluggish nitrogen electroreduction. Herein, we have designed a single-site Cu catalyst on hierarchical nitrogen-doped carbon nanocage support (Cu/hNCNC) for nitrate electroreduction, which achieves an ultrahigh ammonia yield rate (YR) of 99.4 mol h g (2.

The directional assembly of porous organic molecules into long-range ordered architectures, featuring controlled hierarchical porosity and oriented pore channels with defined spatial arrangements, is a fundamental challenge in chemistry and materials science. Herein, using porous organic cages as starting units, we present a cooperative multiscale-assembly strategy enabling the simultaneous alignment of pore channels and directional hierarchical growth in a single step. At the microscopic level, we employed double solvents to manipulate the intermolecular packing of microporous tetrahedral [4+6] imine cages (CC1 and CC3), resulting in pore channel orientation.

Engineering microstructures of Pt and understanding the related catalytic mechanism are critical to optimizing the performance for hydrogen evolution reaction (HER). Herein, Pt dispersion and coordination are precisely regulated on hierarchical nitrogen-doped carbon nanocages (hNCNCs) by a thermal-driven Pt migration, from edge-hosted Pt-NCl single sites in the initial Pt/hNCNC-70 °C catalyst to Pt clusters/nanoparticles and back to in-plane Pt-NC single sites. Thereinto, Pt-NCl presents the optimal HER activity (6 mV@10 mA cm) while Pt-NC shows poor HER activity (321 mV@10 mA cm) due to their different Pt coordination.

Dumbbell-like hetero nanostructures based on gold and iron oxides is a promising material for biomedical applications, useful as versatile theranostic agents due the synergistic effect of their optical and magnetic properties. However, achieving precise control on their morphology, size dispersion, colloidal stability, biocompatibility and cell targeting remains as a current challenge. In this study, we address this challenge by employing biomimetic routes, using ferritin protein nanocages as template for these nanoparticles' synthesis.

Superatoms are special clusters with similar physicochemical properties to individual atoms in the periodic table, which open up new avenues for exploring inexpensive catalysts. Given that the ZrO superatom possesses the same number of valence electrons as a Pd atom, the mechanisms of the Suzuki-Miyaura reaction catalyzed by (ZrO) ( = 1-4) clusters have been investigated and compared with the corresponding Pd ( = 1-4) species to explore superatom-based catalysts for the formation of C-C bonds a density functional theory (DFT) study. It was interesting to find that the catalytic activities of (ZrO) ( = 1-4) towards the Suzuki-Miyaura reaction gradually improved as the cluster size increased.
