Universidad de Zaragoza Shape-controlled continuous synthesis of metal nanostructures 2016 Access copy available to the general public Unrestricted 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. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 7.367 2016 MATERIALS SCIENCE, MULTIDISCIPLINARY 23 / 275 = 0.084 2016 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 13 / 87 = 0.149 2016 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 21 / 166 = 0.127 2016 Q1 T1 PHYSICS, APPLIED 13 / 147 = 0.088 2016 Q1 T1 2.789 2016 Nanoscience and Nanotechnology 2016 Q1 Materials Science (miscellaneous) 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Smith, C.D.
