High-loading and thermally stable Pt1/MgAl1.2Fe0.8O4 single-atom catalysts for high-temperature applications

Single-atom catalysts (SACs) have attracted extensive attention in the field of heterogeneous catalysis. However, the fabrication of SACs with high loading and high-temperature stability remains a grand challenge, especially on oxide supports. In this work, we have demonstrated that through strong c...

Description
Summary:Single-atom catalysts (SACs) have attracted extensive attention in the field of heterogeneous catalysis. However, the fabrication of SACs with high loading and high-temperature stability remains a grand challenge, especially on oxide supports. In this work, we have demonstrated that through strong covalent metal-support interaction, high-loading and thermally stable single-atom Pt catalysts can be readily prepared by using Fe modified spinel as support. Better catalytic performance in N 2 O decomposition reaction is obtained on such SACs than their nanocatalyst counterpart and low-surface-area Fe 2 O 3 supported Pt SACs. This work provides a strategy for the fabrication of high-loading and thermally stable SACs for applications at high temperatures.
