Tuning active sites through metal-support interactions (MSIs) has emerged as an effective strategy to design supported metal catalysts. The development and selection of supports are paramount for achieving the desired catalytic performance, but remain significant challenges. In this presentation, we will discuss using two-dimensional transition metal carbides (MXenes) supported platinum as efficient catalysts. Combining atomic resolution electron microscopy, in-situ spectroscopies and DFT calculations, we demonstrate that the MXenes supports modulate the compositional and electronic structures of the active sites, making them promising platforms with versatile chemical reactivity and tunability for facile design of supported intermetallic nanoparticles over a wide range of compositions and structures.
