Abstract

The 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.

期刊介绍： Established in 2011, Advanced Energy Materials is an international, interdisciplinary, English-language journal that focuses on materials used in energy harvesting, conversion, and storage. It is regarded as a top-quality journal alongside Advanced Materials, Advanced Functional Materials, and Small. With a 2022 Impact Factor of 27.8, Advanced Energy Materials is considered a prime source for the best energy-related research. The journal covers a wide range of topics in energy-related research, including organic and inorganic photovoltaics, batteries and supercapacitors, fuel cells, hydrogen generation and storage, thermoelectrics, water splitting and photocatalysis, solar fuels and thermosolar power, magnetocalorics, and piezoelectronics. The readership of Advanced Energy Materials includes materials scientists, chemists, physicists, and engineers in both academia and industry. The journal is indexed in various databases and collections, such as Advanced Technologies & Aerospace Database, FIZ Karlsruhe, INSPEC (IET), Science Citation Index Expanded, Technology Collection, and Web of Science, among others.
