dc.description.abstract | Single -crystal nanocrystals of catalytic metals and oxides are essential for understanding chemical interactions on well-defined catalyst surfaces. However, a comprehensive understanding of the crystallographic origins for such enhancement has been lacking. This work provides formal evidence of the structure - property relationship through a model study on single -crystal TiO 2 . Our approach involves transient pulse heating to manipulate porosity and phase in epitaxially-grown TiO 2 nanosheets along the (0 0 1) plane. Furthermore, we could introduce high -entropy alloy nanoparticles into the system, which exhibited excellent catalytic activity toward CO oxidation, achieving T 90 at 143 degrees C. This improved performance is attributed to the interplay between the catalytic nanoparticles and the multiphase support, facilitating CO and O 2 adsorption. Our study contributes to a fundamental understanding of structure - property relationships in heterogeneous catalyst systems. Overall, our thermal shock synthesis approach shows much promise for developing single crystal -based advanced nanocatalysts with broad practical implications. | - |
