Nanoparticle synthesis

Definition

Nanoparticle synthesis refers to methods for creating nanoparticles. Nanoparticles can be derived from larger molecules, or synthesized by ‘bottom-up’ methods that, for example, nucleate and grow particles from fine molecular distributions in liquid or vapour phase. Synthesis can also include functionalization by conjugation to bioactive molecules.

    Nanostructures with atomic-level thicknesses have the potential to exhibit unique size-dependent properties. Here the authors fabricate sulfur-doped molybdenum oxide architectures with tunable ring-in-ring morphologies and strong visible- and IR-light absorption, endowing them with a range of photoresponsive properties.

    Doping metal nanoclusters at specific sites is a powerful strategy for tuning their properties. Here, the authors precisely control the alloying sites of bimetallic nanoclusters by replacing entire surface motifs with structurally similar heteroatom motifs, tuning the surface composition motif-by-motif rather than atom-by-atom.

    Control over nanoparticle atomicity has not yet been extended to metal oxides. Here, the authors present the synthesis and X-ray crystal structures of a family of atomically precise ceria nanoclusters, a pivotal step for understanding the relationship between their atomic structure and reactivity.

    Owing to their unique properties, hollow metal nanocrystals demonstrate greater catalytic promise than their solid counterparts. Here the authors produce hollow and inflated palladium nanocrystals with thin shells via a repeated Kirkendall cavitation process, and demonstrate their activity for formic acid oxidation.

    Hollow nanoparticles can be synthesized by galvanic replacement or the Kirkendall effect, which are generally regarded as two separate processes. Here, the authors use liquid TEM to follow the entire galvanic replacement of Ag nanocubes, finding experimental evidence that the Kirkendall effect is a key intermediate stage during hollowing.

    The development of perovskite nanocrystals is limited by poor mechanistic understanding of their growth. Here, the authors systematically study the ligand-assisted reprecipitation synthesis of CH3NH3PbBr3 nanocrystals, revealing the effect of precursor and ligand concentrations on bandgap tunability.
