“…This material contains numerous parallel cylindrical nanopores (pore diameter of 10–400 nm and pore density of 10 8 –10 10 pores cm –2 ) . These well-aligned and uniform nanochannels with precise pore diameters and lengths have been instrumental for confinement-enhanced process analysis − and the synthesis of a diverse range of nanostructures via confined nucleation and growth (e.g., nanowires, nanotubes, and nanobrushes).…”

Engineered nanoporous materials have been extensively employed in the environmental field to take advantage of increased surface area and tunable size exclusion. Beyond those benefits, recent studies have uncovered that the confinement of traditional environmental processes within several nanometer pores exerts unique nanoconfinement effects, such as enhanced adsorption capacity, reaction kinetics, and ion selectivity, compared to their analogous processes without spatial confinement. In this review, we provide a systematic discussion covering the current understanding of nanoconfinement effects reported across diverse fields using similar materials and structures as those being explored in environmental technologies. We further abstract the underlying fundamental physical and chemical principles including molecular orientation and rearrangement, reactive center creation, noncovalent binding, and partial desolvation. Finally, we establish connections between promising nanoconfinement observations and traditional environmental processes to identify challenges and opportunities for the development of innovative functional platforms for environmental applications.

A novel crown-shaped 36-molybdate cluster with organophosphonate-functionalized polyoxomolybdates, (NH4)17Na7H12[Co(H2O)TeMo6O21{N(CH2PO3)3}]6·42H2O, has been successfully synthesized and well-characterized. It owns the highest nuclearity in the family of organophosphonate-based polyoxometalates reported so far. Furthermore, for the first time in the field, we illustrated that polyoxomolybdate could work as an effective heterogeneous catalyst for the Knoevenagel condensation reaction with high TOF (7714 h–1) and good recyclability. Impressively, the catalytic performance of 1 was also tested successfully in a large scale (∼10 g) reaction, where 89% of reaction yield and 3216 of TON were afforded.
