The precise control of the size, morphology and oxidation state of metal particles is an important challenge for the preparation of heterogeneous catalysts
In response to the above-mentioned challenges, the research team used the thermally stable Pt single atom to modify the surface of CeO 2 based on the previous research on the preparation of thermally stable single atoms by the atom trapping method , and deposited Pd on the modified carrier to obtain Two-dimensional PdO x raft structure with H 2 O poisoning and catalyst sintering .
This research uses pre-modified thermally stable metal single atoms on the surface of the support to change the structure and properties of subsequent deposited metals, and provides new ideas and methods for the rational design and development of heterogeneous catalysts
