Fecha de publicación: | 27-sep-2022 | Editor: | American Chemical Society | Citación: | ACS Nano 16(9): 15206-15214 (2022) | Resumen: | Catalyst activity can depend distinctly on nanoparticle size and shape. Therefore, understanding the structure sensitivity of catalytic reactions is of fundamental and technical importance. Experiments with single-particle resolution, where ensemble-averaging is eliminated, are required to study it. Here, we implement the selective trapping of individual spherical, cubic, and octahedral colloidal Au nanocrystals in 100 parallel nanofluidic channels to determine their activity for fluorescein reduction by sodium borohydride using fluorescence microscopy. As the main result, we identify distinct structure sensitivity of the rate-limiting borohydride oxidation step originating from different edge site abundance on the three particle types, as confirmed by first-principles calculations. This advertises nanofluidic reactors for the study of structure-function correlations in catalysis and identifies nanoparticle shape as a key factor in borohydride-mediated catalytic reactions. | Versión del editor: | http://dx.doi.org/10.1021/acsnano.2c06505 | URI: | http://hdl.handle.net/10261/283461 | DOI: | 10.1021/acsnano.2c06505 | ISSN: | 1936-0851 |
