Shape-controlled continuous synthesis of metal nanostructures
A segmented flow-based microreactor is used for the continuous production of faceted nanocrystals.
Flow segmentation is proposed as a versatile tool to manipulate the reduction kinetics and control the
growth of faceted nanostructures; tuning the size and shape. Switching the gas from oxygen to carbon
monoxide permits the adjustment in nanostructure growth from 1D (nanorods) to 2D (nanosheets). CO is
a key factor in the formation of Pd nanosheets and Pt nanocubes; operating as a second phase, a reductant,
and a capping agent. This combination confines the growth to specific structures. In addition, the
segmented flow microfluidic reactor inherently has the ability to operate in a reproducible manner at
elevated temperatures and pressures whilst confining potentially toxic reactants, such as CO, in nanoliter
slugs. This continuous system successfully synthesised Pd nanorods with an aspect ratio of 6; thin palladium
nanosheets with a thickness of 1.5 nm; and Pt nanocubes with a 5.6 nm edge length, all in a synthesis
time as low as 150 s
