Abstract
AbstractThe regulation and stabilization of strong metal‐support interactions (SMSI) in high temperature hydrogen‐rich reaction condition remains a huge challenge due to its structural sensitivity. Herein, tunable SMSI is constructed and stabilized on TiO2 supported Ni catalysts by TiO2 crystal phase engineering strategy, and then a SMSI‐degree‐depended ethanol stream reforming (ESR) performance is demonstrated. Rutile supported Ni exhibited a weakened SMSI with 48.6% coverage, exposing more metallic Ni and Ni‐TiO2 perimeter interface sites, and displayed exceptional H2 yield of 4.7 molH2/molethanol and an ultra‐long stability of 420 h without deactivation at 500 °C. The low reaction energy and high resistance to carbon deposition (0.9 mgc/gcat·h) and Ni0 sintering on Ni/r‐TiO2 catalyst explained its excellent catalytic performance. Furthermore, the effect of well‐defined SMSI structures on the reaction pathway and deactivation mechanism of the ESR is clarified. This work provides a precedent for the tailor and application of SMSI in high temperature hydrogen‐rich reaction conditions.
