Many medical and chemical applications require target molecules to be delivered in a controlled manner at precise locations. Metal–organic frameworks (MOFs) have high porosity, large surface area, tunable functionality are promising carriers for such purposes. Current approaches incorporating based on multistep postfunctionalization. Here, we report novel approach that combines MOF synthesis molecule encapsulation one-pot process. We demonstrate drug dye can encapsulated zeolitic imidazolate...
Colloidal plasmonic metal nanoparticles have enabled surface-enhanced Raman scattering (SERS) for a variety of analytical applications.

Hydrogenation reactions are industrially important that typically require unfavorably high H2 pressure and temperature for many functional groups. Herein we reveal surprisingly strong size-dependent activity of Pt nanoparticles (PtNPs) in catalyzing this reaction. Based on unambiguous spectral analyses, the size effect has been rationalized by d-band electron structure PtNPs. This understanding enables production a catalyst with 1.2 nm, which shows sixfold increase turnover frequency 28-fold...

The oxygen reduction reaction (ORR) is central in carbon-neutral energy devices. While platinum group materials have shown high activities for ORR, their practical uses are hampered by concerns over deactivation, slow kinetics, exorbitant cost, and scarce nature reserve. low cost yet tunability of metal–organic frameworks (MOFs) provide a unique platform tailoring characteristic properties as new electrocatalysts. Herein, we report concept design present stable Zr-chain-based MOFs efficient...
