In the past few decades, there have been many advances in the development of plasmonic nanomaterials and their application in chemical sensing, photothermal therapy, enhancement of photovoltaic device performance, catalysis, solar-driven desalination, among others. To date, nano-sized metals such as gold, silver, and copper have been well-explored for plasmonic applications, however these can suffer from poor thermal and/or chemical stability. Gold is also expensive making it non-ideal material for large scale applications. In a quest to develop plasmonic nanomaterials that are low cost and chemically stable, transition metal nitrides have emerged as strong contenders based on computational studies performed in the last decade. However, the experimental studies on these materials remain scarce. This presentation will highlight some of the recent results from our group on the solid-state synthesis of free-standing plasmonic transition metal nitride nanoparticles [1], their chemical and thermal stability, and photothermal properties [2,3].
