A reflection on ‘Size-tunable rhodium nanostructures for wavelength-tunable ultraviolet plasmonics’

Plasmonic photocatalysis presents a novel approach for controlling heat and light, enabling reactions to take place under milder conditions. In 2016, Zhang and co-workers reported a novel approach in synthesizing rhodium nanocubes with desired sizes and surface plasmon resonances frequency, where the resonance frequency underwent a red-shift from deep UV to 400 nm as the size increased (X. Zhang, P. Li, Á. Barreda, Y. Gutiérrez, F. González, F. Moreno, H. O. Everitt and J. Liu, Nanoscale Horiz., 2016, 1, 75-80, https://doi.org/10.1039/C5NH00062A). In this reflection, we discuss the impact of this work and summarize the research inspired by this initial discovery.
