Tunning the metal-support interaction is a common strategy to regulate the electro and geometric structure of supported metal; However, most of supports were limited to oxides, and how the carbides tune the activity of supported metal in CO2 hydrogenation is still elusive. Herein, Pt nanoparticles dispersed on carbides were fabricated and examined in CO2 hydrogenation to CO. Among the carbides (ZrC, SiC, WC and TiC), Pt nanoparticles supported on ZrC showed the best catalytic activity, with the CO2 conversion of up to around 37% and 99% selectivity towards CO; it also displayed decent stability in the time-on-stream for 60 hours. The mechanistic study indicated the strong metal-carbide electronic interaction enabled the electron transfer from the Pt nanoparticle to ZrC in the Pt/ZrC catalysts. The modulation of Pt electronic structure tunned the adsorption configuration of CO2 and H2, thus enhancing the catalytic performance of Pt nanoparticles in CO2 hydrogenation to CO. This work demonstrates the importance of carbides in modulating the electronic structure of supported metals.
