| description | The invention relates to a boron nitride coated cerium-based platinum group monatomic catalyst as well as a preparation method and application thereof, and belongs to the technical field of catalysts. The preparation method comprises the following steps: S1, dropwise adding a platinum group noble metal salt solution into a cerium oxide carrier dispersion liquid, centrifuging, washing and drying to obtain a cerium oxide loaded platinum group monatomic catalyst; and S2, dispersing the cerium oxide loaded platinum group monatomic catalyst in the step S1 into an organic solvent, adding ammonia borane for reaction, centrifuging, washing, drying and roasting to obtain the boron nitride coated cerium-based platinum group monatomic catalyst. By coating a boron nitride inert layer, utilizing the strong coordination ability of nitrogen-containing heteroatoms and regulating and controlling the microstructure of M atoms, the original M center coordination structure is converted into a high-stability M-N bond (M is platin |
